Use the Quadratic formula, 

x= -b +/- sqrt(b^2-4ac)
     -------------------------
                2a

x= 4 +/- sqrt(16+12)
     ----------------------
              -6

x = 4+/- sqrt(28)
      ---------------
            -6

x = 4 +/- 2*sqrt(7)
      ------------------
              -6

x= 2(2+/- sqrt(7))
     ------------------
            2(-3)


x= 2+/- sqrt(7)
     --------------
           -3

Find the area of the circle <br><br> r = 6 ft
Andru [333]

If the radius of the circle is 6 feet. Then the area of the circle will be 113.097 square feet.

<h3>What is a circle?</h3>

It is the centre of an equidistant point drawn from the centre. The radius of a circle is the distance between the centre and the circumference.

The radius of the circle is 6 feet.

Then the area of the circle will be

Area = πr²

where r is the radius of the circle. Then we have

Area = π × 6²

Area = 36π

Area = 113.097 square feet

More about the circle link is given below.
