Question

A radius of a coin is 2cm.Find the area occupied by the flat surface of the coin when it is placed on table?

Answer 1

Radius of the coin = 2cm
Area of the coin=πr^2
= 22/7*2*2
=88/7
=12.57cm ( approx.)

Therefore, the occupied by the flat surface of the coin when it was placed on the table= 12.57cm(approx.).

Hope this helps you.

Plz mark it as the brainliest answer.

Answer 2

Answer:

Answer will be 12.56 cm because

The formula says π2*2

So π2=22/7*2*2

So π=3.14*2*2

So π=12.57

so area =12.57cm
