Question

if the perimeter and area of a circle are numerically equal, then find the radius
of the circle​

Answer 1

Answer:

radius can be found out by 2 pie r

Answer 2

Step-by-step explanation:

We are given that

perimeter of the circle=area of circle

Thus, 2πr = πr²

so π & π gets cut and r and one r from rhs gets cut

Thus we get r = 2

Let us check it

For perimeter, when r = 2

2πr = 2*3.14*2

=12.56

For area, when r = 2

πr² = 3.14*2²

= 3.14*2*2

= 12.56
