Question

A medium sized paper cone has a diameter of 8 cm and a height of 10 cm what is the volume of the cone

Answer 1

670.21

Explanation:

Formula to find Volume of a cone: V=πr2h

r(Radius) = 8

h(Height) = 10

I just plugged the formula in the calculator and i replaced r with 8 and h by 10.

Written out would be:

V= π (8) 2 (10)

Answer 2

V =167.5516082 cm^3

Explanation:

Volume of a cone is given by

V = 1/3 pi r^2 h

We have the diameter, so we need to get the radius

d= 2r

Divide by 2

d/2 =r

8/2 =r

4= r

V = 1/3 *pi *(4)^2 *10

= 1/3 *pi*16*10

53 1/3 pi cm^3

Let pi = 3.14

V =167.5516082 cm^3
