The circumference of a circle is calculated using the following equation:

Where d is equal to the diameter (the length of a straight line from one side of the circle to the other side).
We know that the diameter of the circle given (also known as AB) is equal to 20 cm.
We can then plug this into the equation and solve for the circumference:

Since the question asks for the answer to be in terms of

, this is as far as we need to go. So
the circumference of the circle is:
or D.
The correct answer is 60 raisins. To get this answer you will write a proportion of M & Ms to raisins and create and equivalent ratio using the number 36.
After you have the proportion set up, you will use cross products to solve for the number of raisins.
You can also use equivalent ratios to find the number of raisins.
Both of these strategies are shown in the attached picture.
17,900 x 0.1296 = 2318.05
2318.05 should be subtracted from 17,900 and it should be somewhere around 15,581.95
This one’s easy if you know how to do the fractions of 5.
The whole trip is 50 miles because 60% of 50 is 30 miles.
3/5 = 0.6
