Question

find the volume of the cylinder. use 3.14 for pi, and round to the nearest hundredth. r = 4.5 inches h = 2 inches

Explanation:

Step1: Recall volume formula

The volume formula for a cylinder is $V=\pi r^{2}h$.

Step2: Substitute values

Substitute $r = 4.5$ inches, $h=2$ inches and $\pi = 3.14$ into the formula: $V=3.14\times(4.5)^{2}\times2$.

Step3: Calculate $(4.5)^{2}$

$(4.5)^{2}=4.5\times4.5 = 20.25$.

Step4: Multiply values

$V=3.14\times20.25\times2=3.14\times40.5$.

Step5: Get final result

$V = 127.17$ cubic - inches.

Answer:

$127.17$
