Question

What is the volume of the cylinder with the height being 12 and radius 11

A. 132 units3
B. 121 units3
C. 1452 units3
D. 1112 units3

Answer 1

C. 1452 units3

Explanation:

Equation for cylinder: π x r^2 x h (Pi times radius^2 times height)

Plug the numbers in the equation: π x 11^2 x 12

When you put it in the calculator, you get 1452π.

(Make sure to put the pi symbol in the calculator to get the answer.)

Answer 2

`\bf \textit{volume of a cylinder}\\\\ V=\pi r^2 h\quad \begin{cases} r=radius\\ h=height\\ ------\\ r=11\\ h=12 \end{cases}\implies V=\pi \cdot 11^2\cdot 12\implies V=1452\pi`
