2pie *rh/2pie r (h+r) =1:2
So h/h+r =1/2 by this h=r
2*22/7 *r(h+r) =616
2r=616 *7/2*22 *r by this r=7 so
vol. Of cylinder =pie rsq *has by put the value of r and h because r=h the volume =1078
So h/h+r =1/2 by this h=r
2*22/7 *r(h+r) =616
2r=616 *7/2*22 *r by this r=7 so
vol. Of cylinder =pie rsq *has by put the value of r and h because r=h the volume =1078
