please give me brainliest!!
Answer:
Working backward
Step-by-step explanation:
Formula: A = πr²
All you have to do is work backwardly
If you have the area, replace the "A" with the area.
You can replace the π with "3.14"
Then divide the area by "3.14"
Then when you get your answer, divide your answer that you got by its square root --> √
Then when you do that....you get your radius....and from there on, you can check it by substituting.
Hope this helped!
