Question

The volume of a sphere is (28÷3)times its surface area.calculate the surface area and the volume of the sphere

Answer 1

Answer:

9856, 91989

Step-by-step explanation:

volume = 4/3 × πr³

surface area = 4πr²

volume = 28/3 × surface area

4/3 × πr³ = 28/3 × 4πr²

r = 28

surface area = 4πr² = 4×22/7 × 28×28 = 9856

Volume = 28/3 × surface area ≈ 91989
