Answer:

87.9645943005 feet

Step-by-step explanation:

The formula for the area of a circle is pi x radius to the power of 2. What number to the power of 2 is 196? 14.

So, the radius is 14.

The formula for the circumference of a circle is pi x diameter. If the radius is 14, the diameter is 28.

28 x pi = 87.9645943005
