A circular pizza with a 16-inch diameter is cut into 8 equal slices. A square pizza is cut into 9 equal-size pieces. To the nearest inch, find the dimensions of the square pizza so that each of its 9 pieces has the same area as one slice of the round pizza. Remember: Circumference = ⋅Diameter, Area = 2 r2 (r is radius). Talk to your teacher or a friend if you need to talk about the problem. The dimensions are. I know this because ___. Optional Extension: If a box is made to exactly fit the square pizza, will the circular pizza fit into the box?

    The square pizza should be 15.03 x 15.03.

    The circular pizza wont fit in a box made for the square pizza, since the diameter of the circular pizza is greater than the side of the square pizza.

    Step-by-step explanation:

    In order to solve this problem we first need to calculate the area of the circular pizza, it's given by the following formula:

    area = pi * (d/2) ² = 3.14 * (16/2) ² = 200.96 square inches

    Each slice has the following area:

    slice = area/8 = 200.96/8 = 25.12 square inches

    The area of a square pizza is given by:

    area = width²

    This is to be divided in 9 squares, so:

    slice = area/9 = (width²) / 9

    25.12 = (width²) / 9

    width² = 25.12*9 = 226.08

    width = sqrt (226.08) = 15.03 inches

    The square pizza should be 15.03 x 15.03.
