Answer:
Hence curved surface area of cylinder is 1496 cm² and its radius is 8.5 cm.
Step-by-step explanation:
The volume of cylinder=πr^2*h
∴ 6358=(22/7)*r*r*28
∴ 6358=22*4*r^2
∴ 6358/(22*4)=r^2
∴ 289/4=r^2
∴ √(289/4)=r
∴ r=17/2=8.5
Curved Surface area of the cylinder=2πrh
=2*(22/7)*(17/2)*28
=2*11*17*4
=88*17
=1496 cm²
