Question

The diameter of a circle is 2 centimeters. What is the circle's area?

Answer 1

3.14 cm²

Explanation:

Given :-

Diameter = 2 cm

To Find :-

Area

Formula Required :-

Area (circle) = πr²

Solving :-

Area = 3.14 x 1 x 1

= 3.14 x 1

= 3.14 cm²

Solution :-

3.14 cm²

Answer 2

We know that:

• Diameter of circle = 2 cm
• Radius = Diameter/2
• Area of circle = πr²

Finding the radius.

• Radius = Diameter/2
• => Radius = 2/2
• => Radius = 1 cm

Finding the area.

• Area of circle = πr²
• => Area of circle = 3.14 x 1²
• => Area of circle = 3.14 x 1 = 3.14 cm²
