Question

The volume of a sphere is 3,000π m3. What is the surface area of the sphere to the nearest square meter?

Answer 1

volume = 4/3 pi r ^3

\[3,000 \pi = \frac 43 \pi r^3\]
\[9000\pi = 4\pi r^3\]
\[2250 \pi = \pi r^3\]
\[2250 = r^3\]
\[r = 47.43\]

surface area = 4pi r^2
\[SA = 4 \pi (47.43)^2\]
got it?

Answer 2

No lol, I got 28255.037544

Answer 3

oh lol sorry...i took the sqrt of 2250 it should be cube root

Answer 4

radius should be 13.1

Answer 5

so surface area = 4 pi (13.1)^2

Answer 6

yup that's a better answer

Answer 7

do you get it?
