Roxanne is measuring the diameter and the radius of different-sized circles. There is a proportional relationship between the radius of the circle in inches, x, and the diameter of the circle in inches, y.
x (radius in inches) y (diameter in inches)
1 2
2 4
9 18
10 20
What is the constant of proportionality? Write your answer as a whole number or decimal.
inches in diameter per inch in radius

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

step-by-step explanation:

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
