Question statement

If $r$ is the radius of the circular end, and $h$ the height (or length) of a solid cylinder then the formulae for the volume, $V$ , and surface area, $S$ , are:

$V=\pi r^2h$

$S= 2 \pi r^2 + 2 \pi rh$ .

Calculate the volume and surface area of the solid cylinder shown below.

Give your answers correct to 2 decimal places.

Give any introductory information the student needs.

Ask the student a question, and give any hints about how they should answer this part.

A cylinder with diameter $\var{2c}$ cm and length $\var{a+5}$ cm.

Surface area: Gap 0. cm $^2$

Volume: Gap 1. cm $^3$

Advice

Note that the question gives you the diameter not the radius.

Make sure that you enter the correct calculation into your calculator.

Give a worked solution to the whole question.
