Question

The volume of a sphere is 500/3π cm3.
Work out the surface area of the sphere.
Give your answer in terms of π.

Answers

  1. The answer is 100π cm².
    Since we are given the volume, equate it to the formula of a sphere to find the radius.
    • 500/3π = 4/3πr³
    • r³ = 500/4
    • r³ = 125
    • r = 5 cm
    Now, substitute this in the formula to find surface area.
    • A = 4πr²
    • A = 4π × (5)²
    • A = 100π cm²
