Answer:
A = 12198.9 in^2
Explanation:
Let's first find the area of the largest circle, and then subtract the area of the smallest circle from it
1) A = Pi * r^2
r = 76 / 2 + 35
A = 3,14 * (76/2 +35)^2
A = 16733.06
2) A = Pi * r^2
A = Pi * (d/2)^2
A = 3,14 * (76 / 2)^2
A = 3,14 * 38^2
A = 4534.16
3) A = A1 - A2
A = 16733.06 - 4534.16
A = 12198.9 in^2
