Problema Solution

A company makes cones out of solid foam. Each cone has a height of

18

inches, and its base has a radius of

3

inches. How much foam is needed to make

25

cones?

Use

3.14

for

π

, and do not round your answer.

Answer provided by our tutors

H = 18 in

R = 3 in

π = 3.14

The volume of one cone is:

V = (1/3)(R^2*π*H)

V = (1/3)(3^2*3.14*18)

The volume of 25 cones is:

25V = 25*(1/3)(3^2*3.14*18) = 4,239 in^3.
