What is the height? If you want help you have to first provide us with all the basic information.

Answer 2

Complete Question:

Circumference of the base of cone is 66cm and height is 12cm

Find the volume.

Solution:

Find the radius:

Circumference = 2πr

2πr = 66

r = 66 ÷ 2π

r = 10.5 cm

Find the volume:

Volume of a cone = 1/3 πr²h

Volume = 1/3 π(10.5)²(12) = 1386 cm²

Answer: Volume = 1386 cm²
