Answer: The radius of a circle with an area of 123 square feet is 6.2571 feet .
Step-by-step explanation:
Hi, to answer this question we have to use the formula for the area of a circle.
Area: π r²
Where "r" is the radius of the circle.
For this case, we have the value of the area:
123 ft² = π r²
So, we have to isolate "r"
123 / π= r²
39.152116 = r²
√39.152116= r
6.2571 ≅ r
