If Ted ate 3 pieces of the pizza the approximate area of the remaining pizza is 159 square inches.
What is a circle?
It is defined as the combination of points that and every point has an equal distance from a fixed point ( called the center of a circle).
The diameter of the large circular pizza = 18 inches
We know the area of the circle is given by:
A = πr²
Where r is the radius of the circle
The radius of the circle = half the diameter of the circle
[tex]\rm r = \frac{Diameter}{2}[/tex]
[tex]\rm r = \frac{18}{2}[/tex]
r = 9 inches
A = π×9²
A = 81π square inches
Each slice area = 81π/8 (total slice = 8)
= 10.125π square inches
If Ted ate 3 pieces of the pizza then the area of the remaining pizza is given by:
= 81π - 3×10.125π
= 81π - 30.375π
= 50.625π
= 159.043 ≈ 159 square inches.
Thus, if Ted ate 3 pieces of the pizza the approximate area of the remaining pizza is 159 square inches.
