Answer:

19cm

Step-by-step explanation:

The volume of the give cone is 21.40 cm³

A cone is a shape formed by using a set of line segments  or the lines which connects a common point, called the apex or vertex, to all the points of a circular base(which does not contain the apex). The distance from the vertex of the cone to the base is the height of the cone.

Given that, A right circular cone has a height of 10 centimetres and a base of 9 cm.

The circumference of the base is 9 cm

Therefore, 2πr = 9

r = 9/3.14×2

r = 1.43 cm

Volume of a cone = πr²h/3

V = 3.14(1.43)²10/3

V = 21.40 cm³

Hence, The volume of the give cone is 21.40 cm³

Answer:

The margin of error = 0.037

Step-by-step explanation:

Explanation:-

Given that the mean of the Population(μ) = 2.38

Given that the standard deviation of the Population(σ) = 0.59

Given sample size 'n' = 950

Level of significance = 0.05

The critical value( Z₀.₀₅) = 1 .96

The margin of error is determined by            

                       [tex]M.E = \frac{Z_{\alpha } S.D}{\sqrt{n} }[/tex]

                      [tex]M.E = \frac{1.96 (0.59)}{\sqrt{950} }[/tex]

                      M.E = 0.037

Final answer:-

The margin of error = 0.037

Answer:

a. 3

Step-by-step explanation:

We solve this question gathering the information given in the question.

June serves 8 guests slices of both pies.

This is soon going to be used

June serves a total of 10 slices of apple pie

This includes the 8 guests which got served both pieces. So 10 - 8 = 2 guests were served only apple pie.

11 slices of blueberry pie.

By the same logic as above, 11 - 8 = 3 guests were served only blueberry pie.

So

8 + 2 + 3 = 13 guests were served at least one pie.

16 - 13 = 3 guests had no pie at all.

Answer:

11860.22 rev/hour

Step-by-step explanation:

The diameter if a cylinder, d = 21.02 inches

Radius, r = 10.51  inches

or

r = 0.875 feet

The linear speed of a point on the cylinder's surface is 18.12 ft/sec.

We need to find the angular speed of the cylinder.

The relation between the linear speed and the angular speed is given by :

[tex]v=r\omega[/tex]

Where

[tex]\omega[/tex] is angular speed

[tex]\omega=\dfrac{v}{r}\\\\\omega=\dfrac{18.12}{0.875}\\\\\omega=20.7\ rad/s[/tex]

or

[tex]\omega=11860.22\ rev/hour[/tex]

So, the required angular speed of the cylinder is 11860.22 rev/hour.

Answer:

67.31

Step-by-step explanation:

27% of $53 is 14.31

$53+$14.31=$67.31

Answer:

$68.05

Step-by-step explanation:

To find out what the total cost of the meal is, multiply 1.07 by 53 * 1.2. I'd multiply 53 by 1.2 first, then multiply the product of that by 1.07.

(53 * 1.2) * 1.07 (Convert 1.2 into 6/5, and 1.07 into 107/100.)

((53 * 6)/5) * 107/100 (Multiply 53 by 6 to get 318.)

318/5 * 107/100 (Cross cancel if needed.)

159/5 * 107/50 (Multiply 159 by 107 to get 17013.)

17013/(5 * 50) (Multiply 5 by 50 to get 250)

17013/250 (Divide 17013 by 250 to get 68.052)

68.052 (Round to the nearest cent)

The meal costs $68.05 in total.
