Question

Volume of a cone is 92400 cubic cm and its vertical height is 72cm. Find the radius of the base of the cone?

Answer 1

Answer:

Volume of cone = 92400 cm^3

h = 72cm

1/3 × 22 /7 × r^2 × h = 92400

1/3 × 22/7 × r^2 × 72 = 92400

22×24/7 ×r^2 = 92400

r^2 = 92400 × 7/22 ×24

r^2 = 5×5×7×7

r = 35cm
