Answer:
The formula for the area of a circle is A = πr^2, where r is the radius of the circle.
We know that the diameter of the circle is 10 ft, so the radius is half of that:
r = 10 ft ÷ 2 = 5 ft
Now we can plug in this value for r into the formula:
A = π(5 ft)^2
A = π(25 ft^2)
A ≈ 78.54 ft^2
Rounding this to the nearest whole number, we get:
A ≈ 79 ft^2
Therefore, the area of the circle to the nearest whole number is 79 square feet.
