where r is the radius of the circle and π is the ratio of a circle’s circumference to its diameter. π (pronounced “pie” and often written “Pi”) is an infinite decimal with a common approximation of 3.14159. You can find out more about Pi here Example of calculating the area...

Calculating the area of a circle is different. It is: Πr² You multiply the pi with the square of the radius. The components of the circle are: Radius: It is the distance from the outside edge of the circle to the center point of the circle. It is the primary component of a ci...
The arc length of a circle is calculated by multiplying the measure of the central angle (in radians) by the radius of the circle. This can be represented by the formula arc length = θ * r, where θ is the central angle and r is the radius of the circle. What is the un...
