The volume of the cylinder is 301.44 cm³. We use the radius that is half of diameter length in the formula for the volume of a cylinder.

The formula for the volume of a cylinder is

V = πr²h

Where

A cylinder has

Using π = 3.14, find the volume of the cylinder!

We find the radius of the cylinder.

r = ½d

r = ½(8) cm

r = 4 cm

The volume of the cylinder would be

V = πr²h

V = (3.14)(4)²(6)

V = 18.84 (16)

V = 301.44 cm³

Hence, the volume of a cylinder with the diameter of 8 cm and height of 6 cm is 301.44 cm³.

The correct option is (c).

3 = 1 + 1/2 + 2/2 + 1/2

The blank number is:

1

Step-by-step explanation:

2/2 = 1

1/2 + 1/2 = 2/2

3 = a + 1/2 + 2/2 + 1/2

3 = a + 1 + 1

3 = a + 2

3 - 2 = a

The correct expression that represents the distance between the friends is 4 steps.

To calculate this

Joy walked 12 steps forward and Shaunte walked 8 steps backward. To find the distance between the two friends, we can add the number of steps they each took, so the expression would be:

12 + (-8) = 12 - 8 = 4

So the correct expression that represents the distance between the friends is 4 steps.

Note that the negative sign in front of Shaunte's steps indicates that she walked backward, and the positive sign in front of Joy's steps indicates that she walked forwards.

The formula distance = speed x time must be used to calculate the duration of a marathon as a function of the runner's average speed.

 1: List the known data. For example, a marathon is 13.1 miles long, and an average runner moves at s miles per hour.

2 :Rearrange the equation to solve for time in Step 2: Time = Speed/Distance

3: Enter the known numbers for distance and speed into the equation: time = 13.1 miles per second.

4: If necessary, simplify the equation. The units of miles will cancel out because the time is measured in hours and the speed in miles per hour, therefore the ultimate unit of time will be hours.

  The final answer  is t = 13.1/s, which expresses the duration of a marathon (in hours) as a function of the runner's average speed (in miles per hour).

Answer:

45 miles per hour is the answer. The unit rate (r) is calculated by dividing the number of miles (d) by the number of hours (t): r = d/t. We know that d equals 135 miles and t equals 3 hours. The unit rate is thus r = 135 miles/3 hours. r is equal to 135/3 miles per hour. r equals 45 miles per hour. 45 miles per hour is the unit rate. I hope this was helpful.

Answer: 14 mg

Step-by-step explanation:

5 mg/2.5 mL = 2 mg per mL

2 mg * 7 mL = 14 mg

Answer:

there are 14 milligrams in 7 mL.

Step-by-step explanation:

to find the number of milligrams in 7 mL, you can use the proportion:

(5 mg) / (2.5 mL) = (x mg) / (7 mL)

Where x is the number of milligrams in 7 mL. To solve for x, you can cross-multiply and divide:

(5 mg) * (7 mL) = (2.5 mL) * (x mg)

x = (5 mg) * (7 mL) / (2.5 mL)

x = 14 mg

Answer: it is 0.05 m

The curves r1(t) = t, 2 − t, 35 + t2 and r2(s) = 7 − s, s − 5, s2 intersect at the point (2.5, -2.5).

An equation is a mathematical statement that asserts the equality of two expressions. It is usually written with an equals sign (=) and expresses the relationships between different variables and constants. Equations are often used to model or describe physical, biological, and chemical phenomena and relationships.

This can be seen by solving the system of equations formed by equating the two curves:

t = 7 − s
2 − t = s − 5
35 + t2 = s2

Solving the first two equations for t and s yields t = 7 − s and s = 2 − t. Plugging these equations into the third equation yields:

35 + (7 − s)2 = s2

By rearranging terms and solving, this equation can be solved for s, which yields s = 2.5. Plugging this value back into the first two equations yields t = 7 − 2.5 = 4.5 and s = 2 − 4.5 = -2.5. Thus, the two curves intersect at the point (2.5, -2.5).

Therefore ,as a result, the answer to the given circle problem is  

√ 1996/(√ 62)3 =0.0915, which is the curvature.

A circle is created in the plane by each point that is a specific distance from another point (center). Thus, it is a curve made up of points that are separated from one another by a defined distance in the plane. Additionally, it is rotationally symmetric the about center at every angle. Every pair of endpoints in a circle's closed, two-dimensional plane are evenly spaced apart from the "center." A circular symmetry line is made by drawing a line through the circle. Additionally, it is rotationally equal about the center at every angle.

Here,

Given: (7, 2t, 3t2) r'(t)

r''(t)= (0, 2, 6t) (0, 2, 6t)

r(t) x r(t) = (6t2, -42t, 14)

(36t4 + 1764t2 + 196) = sqrt (r'(t) x r"(t)

|r'(t)|= sqrt (49 + 4 T 2 + 9 T 4)

We know that t = 1 at (7,1,1), therefore sqrt (36 + 1764 + 196) = sqrt 1996 |r'(t)| = √ (49 + 4 + 9) = √ 62.

The curvature is then equal as√ 1996/(√ 62)3 =0.0915

When limestone is subjected to the heat and pressure of metamorphism, marble is created as a metamorphic rock. Calcite (CaCO3) makes up the majority of its composition, but it also frequently includes other minerals such clay, mica, quartz, pyrite, iron oxides, and graphite.

When limestone undergoes a process known as metamorphism, which involves heat and tremendous pressure, marble is created. The marble's interconnecting calcite crystals are created when the calcite limestone recrystallizes after metamorphism.

Hence, 1000 kg of limestone is subjected to intense heat and high pressure to form marble. So, the statement "about 1000 kg of marble is produced" is applies to the formation of the marble. Hence, option b is correct.

The definition of a linear equation is an algebraic equation in which each term has an exponent of one and the graphing of the equation results in a straight line. An example of a linear equation is y=mx + b.

We can start by using the information given in the problem to set up an equation. We know that:

m < 1 = 6x + 3

m < 2 = 117

We are also given that m < 1 and m < 2 represent different values.

Now we can substitute the second equation into the first equation:

6x + 3 = 117

To solve for x, we can subtract 3 from both sides:
