Step-by-step explanation:
Let the radius be r m
According\ to\ given\ conditionsAccording to given conditions
Volume\ of\ cylinder\=6538{cm}^{3}
= > \pi {r}^{2}h=6538=>πr
2
h=6538
= > {r}^{2}=\frac{6538×7}{22×28}=>r
2
=
22×28
6538×7
= > r=\sqrt{72.25}=>r=
72.25
Hence, radius= \boxed{8.5}
8.5
Than, Curved surface area =2\pi rh
