Question

what is the volume of this cylinder?
round your answer to the nearest hundredth.
20 in
21 in
cubic inches

Explanation:

Step1: Find radius of the cylinder

The diameter is 20 in, so radius $r = \frac{20}{2} = 10$ in.

Step2: Apply volume formula for cylinder

Volume $V = \pi r^2 h$, where $h = 21$ in.
$V = \pi (10)^2 (21) = 2100\pi$

Step3: Calculate and round

$2100\pi \approx 2100 \times 3.14159265 \approx 6597.34$

Answer:

6597.34
