# If the lateral surface area of a cylinder is 94.2 sq cm and its height is 5 cm, then find the radius of its base. (n = 3.14)

 A) 5 cm B) 8 cm C) 3 cm D) 4cm

Correct Answer:
 C) 3 cm

Description for Correct answer:

Given, lateral surface area = 94.2 sq. cm.

=> $$\Large 2 \pi rh = 94.2$$

Therefore, $$\Large r = \frac{94.2}{2 \times 3.14 \times 5} = 3 cm$$
