Find the area of a circle with diameter 10ft.
Use the value 3.14 for , and do not round your answer.
Be sure to include the correct unit in your answer.
The radius of the circle is half of the diameter, so the radius is 10ft/2 = 5ft.
The area of a circle is given by the formula A = πr^2, where A is the area and r is the radius.
Plugging in the given values, we get A = 3.14 * (5ft)^2.
Simplifying, we have A = 3.14 * 25ft^2 = 78.5ft^2.
Therefore, the area of the circle is 78.5 square feet.
