The area of the curved surface of a right circular cylinder is 17.6 m2 and its volume is 14 m3. What is the radius of its base?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. 1.6 m.
(πr2h)/(2πrh) = 14/17.6
⇒ r/2 = 14/17.6
⇒ r = 28/17.6 = 1.59... = 1.6 m (approx)
