What is the exact area of a circle with a diameter of 18 feet?

Kitty [74]

The formula for the area of a circle is

$\pi r^{2}$

We know the diameter, and the radius is half of the diameter. So the radius is 9. Now we plug that into the formula.

$\pi 9^{2} =81 \pi$

So the answer is B, 81 pi square feet

The area of a triangle is 1/2(base)(height) and since this is a right triangle the two legs can be base and height. So the area is 1/2(2x-4)^2 which becomes 1/2(4x^2-16x+16) which is simplified to 2x^2-8x+8. B is the correct answer.
