    Angleslice/360 times area=area of slice

    area=pir^2

    normally pizzas are given in terms of ther diameter

    so 10=diameter

    d/2=r, 10/2=5

    r=5

    area=pi5^2=25pi

    angleslize/360 times 25pi=15

    do math

    times 360 both sides and divide by 25pi both sides

    angle=68.7549 degrees or 1.2 radians
