Determine the equation
First, we calculate the slope (m)




The equation is then calculated as:




Hence, the function is:

To find the probability you do 360/45= 8 to find that there are 8 pieces. Then you find what 1/8 is and that answer is .125 /.13. This means that it is either C or D.
The area is 14.1 since you crossmultiply central angle/360 * sector/pi r2 (36pi) so 45 * 36pi = 5089.38 and then you do sector * 360 which equals 360 only and then you take 5089.38/360 and get 14.1
