Answer:let radius of cylinder = 5x and height = 14x

volume of cylinder= 8800m^

πr^h = 8800

22/7 × 5x × 5x × 14x = 8800

after calculation we find that

x = 2

so after putting value of x

radius = 10m

and height = 28m

then, total surface area of cylinder

=2πr(r+h)

= 2×22/7×10 (10+28)

= 2388.57m^

hope u understand it
