The surface area of a cylinder is given by the formula SA = 2 r 2+ 2rh, where r represents the radius and h represents the height. Solve the formula for h and then use it to complete the following table accurate to two decimal places. (8 marks)

Cylinder A

Surface Area, SA (cm2) 2500

Radius, r (cm) 8

Height, h (cm)

Cylinder B

Surface area 5000

Radius 6

Cylinder C

Surface area 4275

Radius 15
