There are four pairs of different types of shoes in a bag: a pair of boots a pair of sandals a pair of sneakers a pair of flip-flops If you pick shoes from that bag (in the darkness), what is the minimum number of shoes you should pick to be certain that you will have a pair of matching shoes

5

Step-by-step explanation:

i think it might be a but you might want a second opinion

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
