I’ve tried this tons of times but I just don’t get it.

A= 3215.36ft²

Step-by-step explanation:

You have to use the rule for how to find area of the circle, (radius²*3.14)

Your radius is 32, so you have to multiply 32 by 32 you get 1024, after that you have to multiply 1024 by 3.14 or π

32²*3.14=3215.36ft²

Hope this will help you understand!
