Question

A cone has a radius of 6 inches and a height of 20 inches. What is the exact volume of the cone? A) 720π in3 B) 80π in3 C) 240π in3 D) 120π in3

Answer 1

The answer is c. 240π
V=πr² h/3 =π×6²× 20/3 ≈753.98224

Answer 2

The formula for finding volume of a cone is: (π · r² · h) ÷ 3

r = 6
6² = 6 × 6 = 36

h = 20

20 × 36 × π = 240π

Your answer is C. 240π
