### How to Calculate the Area of a Circle

A circle is one of the geometric shapes, sometimes we need to calculate the radius, diameter, area or circumferences of circle. With using excel we can find the radius, diameter, area or circumferences of circle  using formula below :

For example :
1. Create table below
There are 3 cell contain data .
a. Cell B5 is a radius data
If we know radius value, then we can calculate the area of circle
b. Cell B9 is a diameter data
If we know diameter value, then we can calculate the area of circle
c. Cell B13 is a circumferences data
If we know circumferences value, then we can calculate the area of circle

2. Create formula to calculate area of circle
a. On cell E5 type formula :
=PI()*(B5^2)
b. On cell E9 type formula :
=PI()*(B9^2)/4
c. On cell E17 and E18 type formula :
=(B13/(2*PI()))
=PI()*(E17^2)
c. On cell E22 type formula :
=PI()*(B13/(2*PI()))^2

Result from above formula will show on below table
