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.

Volume = approximately 8.6

Step-by-step 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
