Consider two circles, a smaller one and a larger one. if the larger one has a radius that is 15 feet larger than that of the smaller circle and the ratio of the circumferences is 4 colon 1, what are the radii of the two circles?

Part I: 100

Part II: $795

Part 3: 47,700

Step-by-step explanation:

First, to find the total perimeter of the grazing area, you would need to set up an equation to find the perimeter.  

Area = perimeter * apothem / 2.  

Fill in the known values: 500 = P * 10/2. 10 divided by 2 is 5, and 500 divided by 5 is 100. P = 100

To find the cost to place a fence around the total grazing, multiply 7.95 by 100 to get 795.

To solve for the third part, set up a proportion: 1/60 = 100/x

Cross multiply: X = 6,000

Multiply 6000 and 7.95 to get 47,700. $47,700 is the total cost.
