Question

A cone has a radius of 6 inches and a height of 10 inches.

What is the exact volume of the cone?
a. 240π in3
b. 120π in3
c. 40π in3
d. 360π in3

Answer 1

b. 120 in^3
since the formula is a= pi (6)^2 (10/3), 6 squared is 36 which when multiplied by (10/3) becomes 120. Hence pi is multiplied by 120 and we obtain 120pi
