3.14 ⋅ 52
To find the area of the circle, we use the formula A = πr^2, where r is the radius of the circle. In this case, the radius is equal to half of the leg passing through the center, so the radius is 8/2 = 4 inches. Substituting this value into the formula, we get:
A = 3.14 ⋅ 4^2
A = 3.14 ⋅ 16
A = 3.14 ⋅ 52
Therefore, the correct expression is 3.14 ⋅ 52.
