Answer:
I dont really know the answer.. but ill try; if its wrong I am so sorry;
Step-by-step explanation:
First you must get the area of a circle, which is; A= pi r squared
and all you have to do is fill it in like this;
A= 3.14 x 2.0
^
A= 6.28
20ft^2
The length is currently three feet, if you add two feet to three that makes five feet. Five times four is twenty.
I hope this helps!
