Numerical value of the area of circle and circumference of the circle is same. What is the diameter of this circle?1. 4 units2. 2 units3. 1 units4. 0.5 units

Answer» Correct Answer - Option 1 : 4 units

Given:

Circumference of the circle  = Area of the circle

Formula Used:

Circumference of the circle = 2πr

Area of the circle = πr2

Diameter = Radius × 2

Calculation:

According to question

2πr = πr2

⇒ 2 = r

⇒ Radius = 2 units

Diameter = Radius × 2

⇒ 2 × 2 = 4 units

∴ Diameter is 4 units

The correct option is 1 i.e. 4 units
