Question

total surface area of a cylinder is 8448 sq.cm.if the radius of its base is 28cm, what is its height?

Answer 1

T. S.A=8448cm²
radius r=28cm
let heigh of the cylinder be 'h'
TSA of cylinder =2πr(r+h)
8448=2πr(r+h)
2x22/7x28(28+h)=8448
28+h=8448/8x22
28+h=48
h=48-28
h=20cm
hence the height of cylinder is 20cm.
