Hi there! The answer is A. miles
We can find the miles someone would run during the marathon, by using the formula for the perimeter. This is:
2 × width + 2 x length.
Filling in this formula learns us that the distance that is run is measured in miles. The answer is A.
Answer:
153m
Step-by-step explanation:
perimeter of an arc = theta/360 × 2πr
P= 17πm
theta = 20°
17πm= 20/360 × 2 × π × r
153πm = πr
r = 153m
