Question

If the values of area and circumferences of a circle are equal then find the radius of this circle.​

Answer 1

Answer:

r =2

Step-by-step explanation:

2πr = πr^2

if we cut the values -

2= r

Answer 2

As we know that,

Perimeter of circle 2πr

Area of circle = πr2

Given that the perimeter and area of circle

are numerically equal.

Therefore,

πr2 = 2πr

r2– 2r = 0 |

r (r - 2)

→ r = 0 or = r=2
