The formula for the volume and surface area of a sphere will be given to you in the exam, so you will not need to memorise these. \(\text{The volume of a sphere} ~=~ \frac {4}{3} \times \pi \times ...
The area of each of the two circles is \(\pi r^2\)and the area of the rectangle is \(2 \pi r \times h\). The surface area of a cylinder is the area of each of its faces added together.
