Surface Area of a sphere is 5514 sq.cm. What is the volme of the Sphere?
Asked by | 11 Mar, 2008, 11:10: PM
answered-by-expert Expert Answer

surface area= 5514= 4 [pi]. r^ {2}

this gives, r^{2} = (5514*7) / (4*22) 

r = sq root of (5514*7) / (4*22) .

now solve this and put this value of r in the following formula

volume= (4/3) [pi] r^{3}  and then simlify it.
