If the sum of radius and height of a solid cylinder is 20 cm and its total surface area is 880 cm2 then its volume is ?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3
Radius + Height = 20 cm
TSA of cylinder = 880 cm3
2πr(r+h) = 880
2 × 22/7 × r × 20 = 880
r = 7 cm
h = 20 - 7 = 13 cm
Volume of cylinder = πr2h = 22/7 × (7)2 × 13 = 2002 cm3
