Question

A cylinder has a base radius of 7m and a height of

14m. What)is its volume in cubic m, to the nearest tenths place?

Answer 1

Volume = 2155.1 cubic m

Explanation:

The formula for volume of a cylinder is given by:

V = πr^2h, where

• V is the volume in cubic units,
• r is the radius of the circular base,
• and h is the height of the cylinder.

Step 1: Plug in values for r and h to find V, the volume in cubic units and round:

We can now plug in 7 for r and 14 for h in the volume formula. Then, we can round to the nearest tenth at the end:

V = π(7)^2(14)

V = π(49)(14)

V = 686π

V = 2155.13256

V = 2155.1 cubic m.

Thus, the volume of the cylinder is approximately 2155.1 cubic m.
