Q: If radius and height of a cylinder increase by 20% and15% respectively. then what is the % change in curved surface area? 1511 0

Answer : 2. "38%"
Explanation :
Answer: B) 38% Explanation: % Change in Curved Surface Area is given by %Change in radius + %Change in height + %Change in radius × %Change in height 100 ⇒+20 + 15 + 20×15100 = 38%
