Sal's small slice is 1/6 of a circular 16-inch-diameter pizza and his large slice is 1/8 of a circular 24-inch-diameter pizza.

(b) Find the area of the large slice. Give your answer correct to 2 decimal places.


I keep on getting 56.52 but it says its wrong. Can someone please explain how to get this answer please?
