Question

What is the volume of a right circular cone that has a height of 16 inches and a base with a circumference of 4.5 inches.

Answer 1

Volume= approximately 8.6

Explanation:

V=-pir^2h/3w

V=?

r=?

h=16

c=4.5

First we have to change the circumference in radius.

r=c/(pi*2)

R=4.5/(3.14*2)=.7165605

R=.7165605 or .72 rounded

V=3.14*.72^2*16/3 = approximately 8.6
