Question

A cylindrical soup can has a diameter of 3.2 in. and is 5.4 in. tall. Find the volume of the can.

Answer 1

Step 1

State the formula for the volume of a cylinder

$V=\text{ }\pi r^2h$

Where,

$\text{radius(r) =}\frac{diameter}{2}=\frac{3.2}{2}=1.6in$$\text{Height(h)}=5.4in$

Step 2

Find the volume after substitution of values

$\begin{gathered} V=\text{ 3.141592654}\times1.6^2\times5.4 \\ \end{gathered}$$\begin{gathered} V=43.42937684in \\ V\approx43.43in \end{gathered}$

Hence, the volume of the can approximately to 2 decimal places = 43.43 in
