If a decorative sign in the form of a circle has a diameter of 10 feet, what it the area of the sign, to the nearest square foot?

A. 79 ft2 B. 16 ft2 C. 157 ft2 D. 31 ft2

79 ft

To find the area of the sign, you need to use the formula for the area of a circle, which is A = πr^2, where A is the area and r is the radius of the circle.

Given that the diameter of the sign is 10 feet, you can find the radius by dividing the diameter by 2. So, the radius, in this case, would be 10/2 = 5 feet.

Now you can plug the radius into the formula to find the area. The value of π (pi) is approximately 3.14.

A = 3.14 * (5)^2
A = 3.14 * 25
A ≈ 78.5

Since the question asks for the area to the nearest square foot, you need to round the result to the nearest whole number.

So, the area of the sign is approximately 79 square feet. Therefore, the correct answer is A.
