If the surface area of a sphere is 5544 cm2, what is its volume?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 38,808 cm3.
Volume of sphere = 4/3(πr3)
Surface area of the sphere = 5544
4πr² = 5544
⇒ 4 × 22/7 × r² = 5544
⇒ r2 = 441
⇒ r = 21 cm
Volume of sphere = 4/3 × (22/7) × 213
= 38,808 cm
