Question

The curved surface area of a cylinder with radius 3 cm and height 8 cm is equal to $c{m}^2$.

• A. 12 $\pi$
• B. 48 $\pi$
• C. 24 $\pi$
• D. 36 $\pi$

Answer 1

The correct option is B 48 $\pi$

The curved surface area
(CSA) of a cylinder = $2\pi \times r\times h$
CSA = $2\pi \times r\times h$
CSA = $2\pi \times 3\times 8$
CSA = $48\pi c{m}^2$
