The volume of a right circular cylinder of baseradius 10m is 880 metre cube find the tsa of cylinder

Volume of Right Circular Cylinder = Pi x r2 x h
 880 = 22/7 x 10 x 10 x h
 h = 880 x 7 / 22 x 10 x 10
h = 40 x 7 / 10 x 10
h = 4 x 7 / 10
h = 28 / 10 
h =  2.8 m .

T.S.A. of Cylinder = 2 x Pi x r x ( r + h)
                              =  2 x 22/7 x 10 x (10 + 2.8)
                              =   2 x 22/7 x 10 x 12.8
                              =   2 x 22/7 x  10 x 128 /10
                              =   2 x 22/7 x 128
                              =  5632 / 7 
                             =   804.57 m2​.
