the areas of three circular tables are shown.
Circle E: 12.09 ft^2
Circle I: 4π ft^2
Circle U: √600/2 ft^2
To find the radius of each circular table, we can use the formula for the area of a circle:
Area = π * r^2
For Circle E:
12.09 = π * r^2
Dividing both sides by π:
12.09 / π = r^2
Taking the square root of both sides:
r = √(12.09 / π)
For Circle I:
4π = π * r^2
Dividing both sides by π:
4 = r^2
Taking the square root of both sides:
r = 2
For Circle U:
√600/2 = π * r^2
Dividing both sides by π:
√(600/2) / π = r^2
Simplifying:
√300 / π = r^2
Taking the square root of both sides:
r = √(√300 / π)
So the radius of Circle E is √(12.09 / π) ft, the radius of Circle I is 2 ft, and the radius of Circle U is √(√300 / π) ft.
