What is the volume, in cubic meters, of a cylinder with a height of 9 meters and a base radius of 7 meters, to the nearest tenths place?

1 answer

The volume of a cylinder is calculated using the formula V = πr^2h, where r is the base radius and h is the height.

Given:
r = 7 meters
h = 9 meters

V = π(7^2)(9)
V = π(49)(9)
V = 441π

To find the volume to the nearest tenths place, we can use 3.14 as an approximation for π:

V ≈ 441(3.14)
V ≈ 1385.7

Therefore, the volume of the cylinder is approximately 1385.7 cubic meters.
