Question

multiple choice (single... what is the volume of the following cylinder? a 128π b 96π c 48π d 64π

Explanation:

Step1: Find the radius

The diameter is 8, so the radius $r=\frac{8}{2}=4$.

Step2: Use the volume formula

The volume formula of a cylinder is $V = \pi r^{2}h$. Here, $r = 4$ and $h=8$. Substitute the values: $V=\pi\times4^{2}\times8=\pi\times16\times8 = 128\pi$.

Answer:

A. $128\pi$
