- Radius , Squared X PI
If the Diameter is 1 cm , that means the radius is .5 cm
- .5 squared is .25
Next you do is .25 x PI
= 0.78539816339
And that is how you get an area of a Circle.
We are a Year 7 and 8 class at Tamaki Primary School. Our teacher is Mr Janse and we really enjoy sharing our work with others.

The Mathemagicians are at it again!
Enter the radius, diameter, circumference or area of a Circle to find the other three. The calculations are done "live":
The Formula to find the area of a Circle is ...
- Radius , Squared X PI
If the Diameter is 1 cm , that means the radius is .5 cm
- .5 squared is .25
Next you do is .25 x PI
= 0.78539816339
And that is how you get an area of a Circle.
