Step-by-step explanation:
To find the area of a circle, we would use the equation ![\pi r^2](https://tex.z-dn.net/?f=%5Cpi%20r%5E2)
In this case we have the diameter, and that's 42.
The radius of a circle is half of the diameter, therefore the radius would be 21.
Now we know the radius,we can plug that in to our equation.
Your equation should look like this:
![\pi (21)^2](https://tex.z-dn.net/?f=%5Cpi%20%2821%29%5E2)
Pi would be 3.14159
Now, you can solve.
![3.14159(21)^2\\\\3.14159*441\\\\=1,385.44](https://tex.z-dn.net/?f=3.14159%2821%29%5E2%5C%5C%5C%5C3.14159%2A441%5C%5C%5C%5C%3D1%2C385.44)
When you'r edone solving, you should get 1,385.44
1,385.44 ft² would be your FINAL answer.
