The formula of an area of a circle:
![A=\pi r^2](https://tex.z-dn.net/?f=A%3D%5Cpi%20r%5E2)
r - a radius
We have r = 14m. Substitute:
![A=\pi\cdot14^2=196\pi\ m^2](https://tex.z-dn.net/?f=A%3D%5Cpi%5Ccdot14%5E2%3D196%5Cpi%5C%20m%5E2)
If you want an approximate area, you can accept ![\pi\approx3.14](https://tex.z-dn.net/?f=%5Cpi%5Capprox3.14)
Then:
![A\approx196\cdot3.14=615.44\ m^2](https://tex.z-dn.net/?f=A%5Capprox196%5Ccdot3.14%3D615.44%5C%20m%5E2)
