the surface area of sphere is 1386cm.find its volume?

answered-by-expert Expert Answer
Surface area of sphere = 4 * pi * r2 = 1386
From this equation, find the value of r. You will get r = 21/2
 
Now, volume = 4/3 * pi * r3
Put in the value of r in this formula, you will get the volume of the sphere to be 4851 cm3.
