Answer:

50.24\ cm ^2

Step-by-step explanation:

Let's start by finding the radius of this circle.

D=2r\\8=2r\\\text{Divide both sides by 2}\\r=4

Note that in the equation:

A=\pi r^2

"A" stands for area and "r" stands for radius.

Now, let's substitute the given values into the equation.

A=\pi r^2\\A=3.14*(4)^2\\A=3.14*16\\A=50.24\ cm^2
