Answer: To find the area of the circle, we need to know the radius of the circle. We can use the segment drawn from one point on the circle to another point on the circle through the center of the circle, which is labeled as 10 feet, to find the radius.

The segment that passes through the center of the circle is the diameter, so the diameter of the circle is 10 feet. The radius is half of the diameter, so the radius is 10/2 = 5 feet.

Now that we know the radius, we can use the formula for the area of a circle, which is:

A = πr^2

where A is the area and r is the radius.

Substituting π = 3.14 and r = 5, we get:

A = 3.14 x 5^2 = 3.14 x 25 = 78.5 square feet

Therefore, the area of the circle is approximately 78.5 square feet.

So the answer is 78.5 ft2.
