How can you find the area of a circle? give me a good explanation please, ty!​

The area of a circle is pi times the radius squared (Area = pi radius²).

Step-by-step explanation:

The circumference of a circle is the linear distance of a circle's edge. It is the same as the perimeter of a geometric figure, but the term 'perimeter' is used exclusively for polygons.

The following equation describes the relation between the circumference and the radius R of a circle:

C = 2πR

Where π is a constant approximately equal to 3.14159265..

How to find the circumference of a circle

Determine the radius of a circle. Let's assume it's equal to 14 cm.

Substitute this value to the formula for circumference: C = 2 * π * R = 2 * π * 14 = 87.9646 cm.

You can also use it to find the area of a circle: A = π * R² = π * 14² = 615.752 cm².

Finally, you can find the diameter - it is simply double the radius: D = 2 * R = 2 * 14 = 28 cm.

Use our circumference calculator to find the radius when you only have the circumference or area of a circle.

Use this formula: A = π r²

Step-by-step explanation:

A = π r²

What does A = π r² mean? :

(Area = Pi x Radius²)

π = Pi (3.14)

² = squared

Hope this helps! :)
