Question

Find the height and curved surface area of cylinder whose volume is 7040m^3 and radius is 8m

Answer 1

Step-by-step explanation:

volume of cylinder=1/3πr^2h

7040=1/3×22/7×8×8×h

7040×3×7÷22×8×8=h

5×21=h

105=height

now,

curved surface area of cylinder

=2πrh

=2×22/7×8×105

=5280sq.m
