Final answer:
The exact circumference of a circle with a diameter of 10 meters is 10π meters.
Step-by-step explanation:
The exact circumference of a circle with a diameter of 10 meters can be found using the formula for circumference, which is C = πd. Here, d is the diameter of the circle. Given the diameter of 10 meters, we can substitute it into the formula to find the circumference: C = π(10 meters) = 10π meters.
Therefore, the correct answer is
option B) 10π meters
