Answer 1

Given:

The radius of the cylinder is 4cm.

The cylinder is filled with peanut butter of height 12cm.

To find:

The total number of cubic centimeters of peanut butter in the jar.

Explanation:

Using the volume formula of the cylinder,

$V=\pi r^2h$

On substitution we get,

$\begin{gathered} V=3.14\times4^2\times12 \\ V=602.88\text{ cubic cm} \end{gathered}$

Final answer:

The total number of cubic centimetres of peanut butter in the jar is 602.88 cubic cm.
