Final Answer:

Radius: 2.5 yd

Diameter: 5.0 yd

Step-by-step explanation:

Given that the circumference, C, is equal to 5π yards, we can use the formula for the circumference of a circle to find the radius, r:

C = 2πr

Substituting C = 5π yards, we get:

5π = 2πr

Dividing both sides by 2π, we get:

r = 5π / 2π

Simplifying, we get:

r = 2.5 yards

To find the diameter, d, we can use the formula:

d = 2r

Substituting r = 2.5 yards, we get:

d = 2(2.5 yards)

Simplifying, we get:

d = 5.0 yards

Therefore, the radius to the nearest hundredth is 2.5 yards, and the diameter to the nearest hundredth is 5.0 yards.
