Question

57 points ! HELP Identify the volume and surface area of a sphere with great circle area 9π m2 in terms of π. Give your answer in terms of π.

Answer 1

Volume: 36π m³

Surface area: 36π m²

Explanation:

Area = π × r² = 9π

r² = 9

r = 3

Volume = (4/3) × π × r³

(4/3) × π × 3³

36π m³

SA = 4π × r²

= 4π × 3²

= 36π m²
