The Formula for finding the Area of a Circle = [tex]\pi r^{2}[/tex]
[tex]\pi r^{2}[/tex] = 22/7 x [tex]r^{2}[/tex]
22/7 x [tex]r^{2}[/tex] = 68
22 x [tex]r^{2}[/tex] = 68 x 7
[tex]r^{2}[/tex] = 476/22
[tex]r^{2}[/tex] = 21.6363636
r = [tex]\sqrt{21.6363636}[/tex]
r = 4.65149047
It can be rounded up into 4.7 .
So, the radius is 4.7[tex]ft[/tex].
Now to find the Circumference of the Circle, we use the Formula = [tex]2\pi r[/tex]
[tex]2\pi r[/tex] = 2 x 22/7 x 4.7
2 x 22/7 x 4.7 = 29.5428571[tex]ft^{2}[/tex]
It can be rounded up into 29.5[tex]ft^{2}[/tex].
So, the Circumference of a Circle with an Area of 68[tex]ft^{2}[/tex] is 29.5[tex]ft^{2}[/tex].
[tex]ft[/tex] = Feet.
[tex]ft^{2}[/tex] = Square Feet.
