45/1= 45

45/2 = 90

45/3 = 135

45/3 = 180

2. the constant of 2 is 10. the constant of 3 is 2.

the relationship between x and y is that x divided by y equals the constant.

4. x divided by y equals the constant, or

x÷y=c(constant)

Answer:

1. 18.84 in

2. 56.52 cm

Step-by-step explanation:

The circumference of a circle is the distance around the circle. Its found using the formula C = πd or C=2πr. The variable d represents the diameter or the distance from one edge of the circle to the other through the cent. The variable r represents the radius of a circle or the distance from one edge to the center. Use the formula by substituting a diameter or radius then simplify.

1. C = πd = π(6) = 3.14(6) = 18.84 in

2. C = 2πr = 2(3.14)(9) = 56.52 cm
