Final answer:
Marcy traveled a distance of 2355.7 meters around the park.
Step-by-step explanation:
To find the distance Marcy traveled around the circular park, we need to calculate the circumference of the circle. The formula for the circumference of a circle is C = πd, where C is the circumference and d is the diameter. Given that the diameter of the park is 750 m, we can substitute this value into the formula to find the circumference:
C = π * 750 m = 2355.7 m
So, Marcy traveled a distance of 2355.7 meters around the park.
