50pi circumference
96pi area
Step-by-step explanation:
The outer pathway is a circle of radius 25, so the circumference is

The are is pi*r^2 or 625 pi - pi*23^2 = 96pi
This is actually quite simple. all you need to do with a question like this is divide the interest by the principal, and you get the percent answer to the rate. the answer would be approximately 7.3%.
There are 60 minutes in 1 hour. 4 x 60 = 240
240 cups in 2 hours
240 /16 cups =
