Answer 2

A 5 rupee coin is cylindrical in shape having radius r and haight h.

A 5 rupee coin is cylindrical in shape having radius r and haight h.TSA of a cylinder is given by 2πr(r+h)

A 5 rupee coin is cylindrical in shape having radius r and haight h.TSA of a cylinder is given by 2πr(r+h)Thus, the total surface area of the cylinder can be calculated by using the formula 2πr(h+r)
