Answer 2

Answer :

›»› The radius of the circle will be 2.

Given :

• The perimeter and the area of a circle are equal.

To Find :

• The radius of the circle = ?

Solution :

As we know that

→ Perimeter of circle = 2πr

→ Area of circle = πr²

The perimeter and the area of a circle are equal.

According to the given question,

→ Perimeter of circle = Area of circle

→ 2πr = πr²

→ 2πr = π r * r

→ 2r = r * r

→ 2 = r

→ r = 2

║Hence, the radius of the circle will be 2.║

Additional Information :

Circle :

• Circle is a round shape shaped figure.

• Circle has no corners or edges.

• A circle can be defined as a closed, two-dimensional curved shape.

• A circle has 5 part : Diameter, Chord, Radius, Arc and tangent.

What is the formula of Area of circle ?

➝ Area of circle = πr²

Where,

• The value of π is 22/7 or 3.14.
• r is the radius in cm or m.
