If the perimeter and the area of a circle are numerically equal, then the radius of the circle is:

(a) 2 units (b) ¶ units (c) 4 units

⠀⠀ || ✪.ANSWER.✪ ||

We Know,

★ Perimeter of Circle = 2πr .

Perimeter of Circle = 2πr .★Area of Circle = πr² .

Where, r is radius of circle

A/C to Question ,

( If the perimeter and the area of a circle are numerically equal )

So,

( Perimeter of Circle = Area of Circle )

➡ ( 2πr ) = πr²

➡ r²/r = 2π/π

➡ r = 2 .

Thus,

★ The Radius of the circle is (r) = 2unit .
