What is the circumference of a circle with a radius of 80 inches?(Use 3.14 for pie)

For circumference, you would use the formula: C=(2)(3.14)(r)
In this case, r=80. Therefore 2x80=160
160x3.14=502.4
C= 502.4 in

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 correct graph is the second one, with the points being at (-6,0), (2,0) and reaching down to (-2,-8)
