    To solve this problem, we begin by getting the whole area of the pizza. Because pizzas are depicted to be round, we will be getting the area of a circle.

    The formula for getting the area of a circle: A = Pi * r^2

    Pans are measured by their diameter, but we need the radius. The radius is simply half of the diameter.

    8 / 2 = 4.

    Now we have our radius.

    Plug in our values.

    A = 3.14 * 4^2

    Take care of 4^2

    A = 3.14 * 4^2 = 3.14 * 4 * 4 = 3.14 * 16

    Now just multiply 3.14 and 16 together.

    3.14 * 16 = 50.24

    Ok, now we need to get the area for an individual slice of pizza. The pizza is cut up into 5 slices.

    So, each slice would be 1/5 of the total area.

    50.24 * 1/5

    To make our lives easier, convert 1/5 into a decimal. Just divide the top by the bottom.

    1 / 5 = 0.2

    50.24 * 0.2 = 10.048

    Now we need to round this to nearest inch.

    10.048 ≈ 10

    So, each slice of pizza has an area of 10 square inches.
