### Solved Example

The below solved example may be useful to understand how the values are being used in the mathematical formulas to find the area, circumference & diameter of a circle.

Example Problem :
Find the area, circumference & diameter of a circle having the radius of 5 cm?

Solution :
The given

Step by step calculation
formula to find area = π r2
substitute the values
= π x 52
= 78.5714

formula to find circumference = 2 π r
substitute the values
= 2 x π x 5
= 31.4286

formula to find diameter = 2 r substitute the values
= 2 x 5
= 10
