r=2

please make me brainlist

Answer 2

Solution

Given :-

• if the perimeter and area of a circle are numerically equal

Find :-

• Radius of circle

Explanation

Formula,

★ $\boxed{\tt{\red{\:Perimeter_{circle}\:=\:2πr}}}$

★ $\boxed{\tt{\green{\:Area_{circle}\:=\:πr^2}}}$

Where,

• r = Radius of circle .

According to question,

➡ Perimeter of circle = Area of circle

➡ 2πr = πr²

➡ r²/r = 2π/π

➡r = 2 .

Hence

• When perimeter & area of numerically equal , then radius will be = 2 .
