Question

The volume of a right circular cone is 1,526.04 in. If the height of the cone is 18 in, what is the diameter of the cone?

(User = 3.14)

A. 9 in
B. 18 in
C. 81 in
D. 40.5 in

Answer 1

all u need to do is look for the relation b/w the values given to u

Explanation:

here it would be the formula of finding the volume of a cone

=> (1/3) (pi) (r)^2 (h) = 1526.01

=> r^2 = (1526.01 x 3) / ( 3.14 x 18)

=> r = √80.99

=> r = 8.99

therefore, diameter = 2 x radius

= 2 x 8.99 = 17.9
