Answer:

B

Explanation:

The area of a circle can be found using:


a=\pi r^2

First, we need to find the radius

The radius is half of the diameter, or

r=d/2

We know the diameter is 6, so we can substitute 6 in for d

r=6/2

r=3

Now, we can substitute 3 in for r in the area formula


a=\pi r^2 \\a=\pi 3^2\\a=\pi 9

Multiply 9 and pi

a=28.2743338823

Rounded to the nearest hundreth

This is about 28.26, so the correct answer is B

B. 28.26 ft^2
