To find the circumference of a circle you do 2(pi)(radius) and we know the radius is 7 so we just plug all the numbers into the equation and solve

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.

The slope best fit isc. 1/6 mile per hour
