We would first have to find the area of pizza(πr^2),then devide it by ten,which would make the equation:

[π(18÷2)^2]÷10
=(9^2π)÷10
=81π÷10
=8.1π inch^2

Thus the answer is 8.1π.

Hope it helps!

Hey!


First, let's find the area. The formula for finding area of a circle is: π · r²


Radius is ½ of the diameter. Divide the diameter by 2 to get the radius.


d = 18

18 ÷ 2 = 9


r = 9

r² = 9 × 9 = 81


The area of the whole pizza is 81π. There are 10 slices. Divide the area of the whole pizza by 10 to find the area of 1 slice.


81π ÷ 10 = 8.1π


That means each slice is 8.1π inches²
