Answer:
11 inches
Step-by-step explanation:
The area of a circle can be found using:
We already know that the area is 380, so we can substitute 380 in for a.
380=
Now, we need to find the radius. To do this, we need to get r by itself
First, divide both sides by pi
120.95775675=r^2
Since r is being squared, we need to take the square root of both sides
10.9980796846=r
If we round to nearest whole number, our radius is 11 inches
