Answer:

[tex]114.93 ft[/tex]

Step-by-step explanation:

[tex]\pi  = 3.14[/tex]

Given formula to find the area:

[tex]\pi  * r^2[/tex]

Find radius first:

[tex]Circumference = \pi  * 2 * r[/tex]

The circumference in this situation would be 38 feet.

[tex]38ft = \pi  * 2 * r[/tex]

[tex]38 ft = 3.14 * 2 * r[/tex]

[tex]3.14 * 2 = 6.28[/tex]

[tex]38ft = 6.28 * r[/tex]

Since we need to find radius, do division to 38 by 6.28.

[tex]38ft / 6.28 = 6.05[/tex]

Our radius is 6.05

Now back to the original formula which is:

[tex]\pi  * r^2[/tex]

Substitute:

[tex]A = 3.14 * 6.05^2[/tex]

[tex]6.05^2 = 36.6[/tex]

[tex]A = 3.14 * 36.6[/tex]

[tex]==> 114.93ft[/tex]
