Question

when the circumference of the circle and the area of the circle are numerically equal then the radii of the circle is

Answer 1

Let radius of circle be 'r'

Given:

Circumference of circle=area of circle

2πr = πr²

2r=r²

2=r

Therefore, radius is 2units

Answer 2

Answer:

Step-by-step explanation:

circumference =2(pi) r

are =(pi)r^2

(pi)r^2=2(pi)r

r^2=2r

r=2
