Answer:
4.399231874 or radical (60.8/pi)
btw radical is square root
Step-by-step explanation:
Since the area of 1/4 (90/360) of the circle is 15.2 ft^2, the area of the whole circle must be
15.2*4 = 60.8.
Now, we can work backwards to find the radius using the are formula. Let's say the radius is x.
x^2pi = 60.8
x^2 = 60.8/pi
x = radical(60.8/pi)
