Question

a cylindrical fish tank has a radius of 6 inches and a height of 20 inches. which expression best represents the volume of the tank, $v = pi r^{2}h$?
a $pi(6)^{2}(20)$
b $pi(6)(20)^{2}$
c $2pi(6)^{2}(20)^{2}$
d $2pi(6)(20)$

Explanation:

Step1: Identify radius and height values

Given $r = 6$ and $h=20$.

Step2: Substitute into volume formula

Substitute $r = 6$ and $h = 20$ into $V=\pi r^{2}h$, we get $V=\pi(6)^{2}(20)$.

Answer:

A. $\pi(6)^{2}(20)$
