Question

What is the volume of a cylinder with a

height of 18.5 m and a base with a
diameter of 5.2 m, to the nearest tenth of a
cubic meter?

392.9 m^3 is the real answer

Answer 1

Yes it is is 392.9 m^3

Explanation:

Volume of cylinder is π*r^2*h, π times radius squared times height.

Since the diameter is 5.2, the radius is 2.6 (half of it). 2.6^2 = 6.76, and the height is 18.5, 6.76*18.5 = 125.06. Multiply it by pi to get 392.887577258, round it to 392.9, The volume is 392.9 cubic meters.
