A cylinder of radius r cm and height h cm has a curved surface area A cm². Where –
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.
The Answer is Letter A.....
