Solving forr
r=(3V
4π)⅓=(3·802
4·π)⅓≈5.76362m
Answer:
r = 5.8 meters
Step-by-step explanation:
The volume formula is V = (4/3)(pi)(r^3), where r is the radius.
Solving for r, we get first 3V = (4pi)(r^3), so that r^3 = (3V)/(4pi)
or in this case, r^3 = 3(802 m^3) / (4pi) = 191.5 meters^3
Taking the cube root of both sides yields r = 5.8 meters

2. 7/8, .875, 87.5%
Step-by-step explanation:
Add all of our balloons popped, which is 40. striped balloons popped is 17, so 17/40. which is 0.425 and 42.5%
for polka dots, it would be 7/8. 35/40 simplest form is 7/8 then we get .875, which is 87.5%

What is the height of the cone.
By examining this image:
⇒ we see a right triangle made up of sidelength of h, 8, and 17
⇒ we know this is a right triangle because there is a little square
⇒between lines of length 8 and h
⇒ which indicates this angle is 90 degrees
⇒ which indicates we have a right triangle
Since we have a right triangle
⇒ we can use the Pythagorean Theorem
Definition of Pythagorean Theorem: square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides.*look at the image attached for a better explanation
Now let's form an equation (based on the Pythagorean Theorem)
[tex]h^2 + 8^2 = 17^2\\h^2 = 17^2- 8^2h^2 = 289 - 64 = 225\\h^2 = 225\\h = 15[/tex]
Thus h = 15cm

The equation using supplementary angles is x + 100° + 3x = 180°. Then the value of 'x' is 20°.
What is an angle?The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360°.
The two angles are said to be supplementary angles if their sum is 180 degrees.
By the above property of angle, the equation is written as,
x + 100° + 3x = 180°
Simplify the equation, then we have
x + 100° + 3x = 180°
4x = 80°
x = 80° / 4
x = 20°
The equation using supplementary angles is x + 100° + 3x = 180°. Then the value of 'x' is 20°.

18 meters by 14 meters
Step-by-step explanation:
18 meters by 14 meters
Area of rectangle is base times height (AKA length times width or however you wish to call the dimensions).
This question is a system of equations question. We can make two equations. We know that every rectangle must have 2 "lengths" and 2 "widths" (4 sides in a rectangle). Since Maria only has 64 meters of fencing, we get the equation:
2L+2W = 64
Now we know the area enclosed must be 252 so we have:
L* W = 252
Rewriting the second equation we get:
Plug this into first equation to get:
(multiply everything by L)
Solving the quadratic tells us L can be 18 or 14. Let's consider if L is 18 first by plugging 18 back into the second equation to get 18 * W = 252 which gives us W = 14. If we do the same for when L = 14, we get that W = 18.
Now you might wonder why we have 2 possible combinations, that's because in reality, it doesn't matter which one we label as length (L) or width (W).
What is the area of the trapezoid?
A trapezoid resting on a base. The top side is labeled 14 in. The bottom side is labeled 30 in. The left side is labeled 15 in. The right side is labeled 20 in. Where the left side and the bottom side meet there is a right angle box.
Answer:
29.5 inches squared
Step-by-step explanation:
The formula for the area of a trapezoid is [tex]\frac{base1 + base2 * height}{2}[/tex],
so base1 = 14 inches and base2 = 30 inches
since there is a right angle, you know that the height must equal the length of the left side, so the height = 15 inches
then, 14+30+15=59 and 59/2=29.5
therefore, your answer would be 29.5 inches squared

Jackson has a cube. Each edge of the cube is 5 centimeters long.
After the paint dries, Jackson cuts the cube in half. He makes the cut along the diagonal of one pair of
parallel faces. Rounded to the nearest thousandth, the diagonal has a length of 7.071 centimeters. Once
the cut is made, Jackson has two identical triangular prisms.
What is the combined area, in square centimeters, of the surfaces of the two prisms that were not painted?
Answer:
35.355 cm
Step-by-step explanation:
if u imagine the 3D cut triangle but at a different angle, u would imagine the legnth of the parallelogram being 7.071 which is the hypotenuse of the triangle... along with the hypotenuse given, they also gave the side lenght of the parallelogram which is 5cm... 5 x 7.071 = 35.355 cm

WILL GIVE BRAINLIEST FOR RIGHT ANSWER! :)
Answer:65.8
Step-by-step explanation:
Now we have: 70 percent of 94 = 65.8
Question: What is 70 percent of 94?
We need to determine 70% of 94 now and the procedure explaining it as such
Step 1: In the given case Output Value is 94.
Step 2: Let us consider the unknown value as x.
Step 3: Consider the output value of 94 = 100%.
Step 4: In the Same way, x = 70%.
Step 5: On dividing the pair of simple equations we got the equation as under
94 = 100% (1).
x = 70% (2).
(94%)/(x%) = 100/70
Step 6: Reciprocal of both the sides results in the following equation
x%/94% = 70/100
Step 7: Simplifying the above obtained equation further will tell what is 70% of 94
x = 65.8%
Therefore, 70% of 94 is 65.8

last week you walked your dog 12.405 miles. this week you walked your dog 15 miles. how many fewer miles did you walk last week than this week?
The dog walked 3 miles less in last week than this week.
What is approximation?An approximation is anything that is similar, but not exactly equal, to something else. A number can be approximated by rounding.
Given that, last week you walked your dog 12.405 miles. this week, you walked your dog 15 miles.
The dog walked in last week approx = 12 miles
The dog walked this week = 15 miles
The fewer miles did he walked = 15-12 = 3
Hence, the dog walked 3 miles less.
