Question

Find the surface area and volume of the

sphere. Round your answers to the
nearest hundredth.
14 m

Answer 1

We know that,

• Volume of sphere = 4/3 πr³

where r is radius

Volume = 4/3 × 3.14 × (14)²

= 4/3 × 3.14 × 2744

= 4/3 × 8616.16

= 34464.64/3

= 11488 m³ (approx)

Surface area of sphere = 4πr²

= 4 × 31.4 × (14)²

= 4 × 3.14 × 196

= 12.56 × 196

= 2461 m² (approx)
