Question

find the volume of a cylinder which is formed by revolving plastic sheet of dimensions 14cm ×7cm if it is folded along its length and breadth also

Answer 1

Answer:

The perimeter of the base of the resulted cylinder is 7cm,and height is 14cm.                                     Step-by-step explanation:

2πr=7cm

r=7/2π cm.

volume of resulted cylinder=πr^2h.

                                             =π*7/2π*7/2π*14

                                             =54.5681818182cm^3
