Step-by-step explanation:
πr²h=2500π
r²=2500/49
r=50/7 cm
Lateral SA=2πrh
=2*22/7*50/7*49
=2200 cm²
TSA=2πrh+2πr²
=2200 + 2*22/7*50/7*50/7
=2200+320.7(app.)
=2520.7 cm²

Step-by-step explanation:
volume of cylinder= πr²h=2500
r= (2500/πh)^½
r=(2500/49π)^½
r=50/(9×π^½)
total surface area=2πr(h+r)
T.S.A.= now put the value and get your answer.
