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)

Factorise using the difference of two squares:<br> I)4x squared-(2x+3) squared

alex41 [277]

4x² - (2x + 3)²
4x² - (2x + 3)(2x + 3)
4x² - (2x(2x + 3) + 3(2x + 3))
4x² - (2x(2x) + 2x(3) + 3(2x) + 3(3))
4x² - (4x² + 6x + 6x + 9)
4x² - (4x² + 12x + 9)
4x² - 4x² - 12x - 9
-12x - 9
-3(4x) - 3(3)
-3(4x + 3)
