Adyson Anthony · Answer 1

Recall that the volume of a sphere is described as 4/3pi (r^3). substituting in 21 for r, we get (4 * (21^3) / 3) pi. this simplifies (I think) to 12068pi. adding the units, you get 12068pi m^3

John · Answer 2

V = (4/3) pir^3

r=21

V = (4/3) pi21^3

V = (4/3) pi9261

V = (37044/3) pi

V=12348pi

V=12348pi m³ or aprox 38792.378016 m³
