A cylinder of radius r cm and height h cm has a curved surface area A cm². Where –
- A = 2πrh cm²
a) We are asked to find formula for h.
First, overturn the equation
Divide both sides by 2πr
b) Again, we are given –
- Curved surface area, A = 93 cm²
- Radius, r = 2.5 cm
- π = 3.1

- Henceforth, height of the cylinder is 6 cm.
