Formula for finding the area of a circle: [latex]A = pi r^2[/latex] We need to radius but we only have the diameter. Luckily for us, if you have the diameter, you have the radius. Because the radius is the diameter over 2. 10 / 2 = 5 Plug in the values. A = (3.14)5^2 A = (3.14)25 A = 78.5 So, the answer is 78.5.
