A circle has a diameter of 6.4 feet. Which answer is closest to the area of the circle? Use 3.14 for 𝜋.
40.19 ft2
32.15 ft2
10.05 ft2
128.61 ft2
The formula for the area of a circle is A = πr^2, where r is the radius of the circle. Since the diameter is given as 6.4 feet, the radius would be half of that, which is 3.2 feet.
Plugging this value into the formula, we get: A = 3.14 * (3.2)^2
A = 3.14 * 10.24
A ≈ 32.15 ft^2
Therefore, the answer closest to the area of the circle is 32.15 ft^2.
