Answer 3

I agree with 21

Answer 4

now I'm checking 22

Answer 5

Okay.

Answer 6

22 looks good too

Answer 7

Thank ya.

Answer 8

np

Answer 9

Sphere Volume = 4/3 * PI * r^3
r^3 = Sphere Volume / (4/3)*pi
r^3 = 4,000 / (4/3)
r^3 = 3,000
r = 14.4224957031

Sphere Area = 4 * pi * r^2
Sphere Area = 4 * pi * 14.4224957031^2
Sphere Area = 2,613.9104229403

Yes, 2,614 is correct
