Question

Find the surface area of a sphere that has a volume of 288pi cu.in
a)48pi
b)144pi
c)20,736pi

Answer 1

v=4/3pr^3 so in your case r=6(just enter the rumbers in the formula) than surface area is 4pr^2 so we have 4px36=144pi

Answer 2

Oh! Thank you Sparrow2!

Answer 3

welcome

Answer 4

hint:
the volume of a sphere of radius R is:
\[V = \frac{{4\pi }}{3}{R^3}\]

Answer 5

so we can write:
\[{R^3} = \frac{{3V}}{{4\pi }}\]

Answer 6

now you have to solve that last equation for R, what do you get?
