Answer:

volume of the sphere = 2143.57units³

Explanation:

Given that the area of a sphere = 256πunits²

volume of the sphere = ?

recall that the area of a sphere = 4πr²

256π = 4 πr²

divide both sides by 4π

256π/4π = 4πr²/4π

64 = r²

squaring both sides

r = √64

r = 8units

now to calculate the volume of the sphere,

recall that

volume of the sphere = 4π r³/3

volume of the sphere = 4π 8³/3

volume of the sphere = 4π 512/3

volume of the sphere = 4 × 3.14 × 170.667

volume of the sphere = 2143.57units³
