The coefficient of determination represents the percentage of the data that is the closest to the line of best fit.
the total variation in y can be explained by the linear relationship between x and y
Since you are solving for diameter, and the equation is given to you, just isolate the variable for diameter (d).
(C)/π = (πd)/π
d = C/π is your formula you will use.
Plug in 56 for C
d = 56/π
d = ~17.825

Answer:
x= - 16
Step-by-step explanation:
substitute y=0 then multuply both sides move the variable to the left and change the sign.
Just set it equal to zero and solve using the quadratic equation.
