The radius of base and curved surface area of a right cylinder is 'r' units and 4πrh square units respectively. The height of the cylinder is :
A. $$\frac{{\text{h}}}{2}$$ units
B. 1h units
C. 2h units
D. 4h units
Answer: Option C
Solution (By Examveda Team)
Radius of the base = r unitsCurved surface area of a right cylinder = $$4\pi {\text{r}}h$$
Curved surface area of cylinder = $$2\pi {\text{RH}}$$
∴ According to the question,
$$2\pi {\text{rH = }}4\pi {\text{rh}}$$
⇒ Height of cylinder = 2h units
