Final answer:
The area of a circle with a diameter of 17yd is 72.25πyd².
Step-by-step explanation:
The area of a circle can be found using the formula A = πr², where A is the area and r is the radius of the circle. Since we are given the diameter of the circle, we need to first find the radius by dividing the diameter by 2.
Given that the diameter is 17yd, the radius would be 17yd/2 = 8.5yd.
Now we can calculate the area using the formula: A = π(8.5yd)² = π(72.25yd²) = 72.25πyd².
