First, you would need to find the area of the circle/pizza . . .
Formula of finding area → pi*r² (Pi * the radius of the circle/pizza²) --- Once you have found the area, you would need to divide the result by the number 12 since there is a total of 12 slices in the pizza. --- This is how you would find the area of one slice of pizza. __________________ I hope this helps you. Have a great day! :)
