Answer:
this might help
Step-by-step explanation:
Remember, to find the area of a circle, you need to multiply pi by the radius squared
The area, 'A', of the circle is 153.86 inches squared
'π' is pi, an irrational number with a value of approximately 3.14
'r' is the radius, which is what we are solving for here
We plugged our information into the A=πr2 formula
We get "r=7", which means the radius of the circle is 7 inches!
