Equal to the area. Area of circle is
![\pi r^2](https://tex.z-dn.net/?f=%20%5Cpi%20r%5E2)
This equals to
![4 \pi](https://tex.z-dn.net/?f=%204%20%5Cpi%20)
due to 2^2.
Circumference is
![2 \pi r](https://tex.z-dn.net/?f=2%20%5Cpi%20r)
This equals to
![2 \pi (2)](https://tex.z-dn.net/?f=2%20%5Cpi%20%282%29)
When you multiply the 2 and the radius together, they equal to 2^2.
