Answer: Undefined
Step-by-step explanation:
The slope of the line is undefined because the slope of the line is the change in y over the change in x. The change in x is 0 but the change in y is a number. Any number divided by 0 must be undefined.
We are looking for the inner perimeter of the track. Since there are two semicircles, these mix to form one full circle so we can use the formula to find the circumference of the circle with a diameter of 60 m, which was given to us. With a diameter of 60m, the radius will be 30m. Now we can solve this problem.
C = 2πr
C = 2π(30)
C = 60π
The semicircle ends of the track are a distance of 60π m, and now we just need to add the lengths of the inner track which are 100 m each. So:
P = 60π + 100m + 100m
P = 200 + 60π
P = 388.5 m
It would be 50,000 since the 5 in the other number is in the thousands place so just multiply that by 10 in place value.
