Question

give the formula to find the total surface area of 5 rupees coin​

Answer 1

Answer:

A 5 rupee coin is cylindrical in shape having radius rr and haight hh.

TSA of a cylinder is given by 2\pi r(r+h)2πr(r+h)

Thus, the total surface area of the cylinder can be calculated by using the formula 2\pi r(h+r)2πr(h+r)

Answer 2

Answer:

2×pi×r (r+h)

Step-by-step explanation:

coin is in the form of cylinder

and cylinder's total surface area is 2pi×r (r+h)
