Answer:
2820.36 feet
Step-by-step explanation:
First we need to find the length of the outer corridor, and we do that by finding the length of the circunference with a radius of 25 feet:
C = 2 * pi * r = 2 * pi * 25 = 157.08 feet
Now, as Heather walks the outer corridor 17 times and the length of 6 spoke aisles (the radius of the circunference), we have that the total distance she walks is:
Distance = 17 * 157.08 + 6 * 25 = 2820.36 feet
The answer is 2.5 cm
First, you multiply 4 and 12, and you get 48
Then you take 120 and you divide it by 48.
This leaves you with 2.5
To check you multiply 2.5, 4, and 12
You divide 2/4 by 2 and you should get 1:2
