Question

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

Answer 1

Answer:

Hope this helps

Step-by-step explanation:

Perimeter= 2πr

Area= πr^2

If they are equal that means

2πr=πr^2

π gets cancelled due to division and then we are left with

2r/r×r

1r gets cancelled with 1r then we are left with

2/r

so radius= 2units

Answer 2

Answer:

Perimeter = 2πr

Area = πr²

if value of perimeter and area are X

2πr = x

πr² = x

2πr = πr²

2r = r×r

2 = r

so the radius is 2
