Question 274130: pie with a diameter of 12 inches is cut into 8 equal slices. Each slice of the pie has an area of ______ square inches Answer by CharlesG2(834) (Show Source):
You can put this solution on YOUR website! pie with a diameter of 12 inches is cut into 8 equal slices. Each slice of the pie has an area of ______ square inches
area whole pie = pi * (diameter/2)^2 = pi * radius^2
area of slice = 1/8 * pi * (diameter/2)^2 = 1/8 * pi * radius^2
radius = diameter/2 = 12/2 = 6
area slice = 1/8 * pi * 6^2
= 1/8 * 36 * pi (so 36pi is area whole pie)
= 36/8 * pi
= 9/2 * pi
