The curved surface area of a right circular cylinder of height 28 cm is 176 cm2. The volume (in cm3) of cylinder is (Take π = 22/7)
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 88.
Height of cylinder = 28 cm
Curved surface area of cylinder = 2πrh = 176 cm2
ATQ -
2 × (22/7) × r × 28=176
r = 8/8
r =1 cm
Volume of a cylinder = πr2h = (22 ×1 × 1 × 28)/7 = 88 sq cm
