For calculating the area of a circle, we have to use the formula A = [tex] \pi r^{2} [/tex]
We also know that the diamter is twice the length of the radius. So, the radius is 5 inches.
So now, all we have to do is multiply [tex] \pi [/tex] by [tex]5^{2} [/tex], and we get an answer of around 78.5 square inches
Hope I helped!! xx
