Given the below expression.

a) Prove that S can be divided by 15
b) Show that S has a minimum of 30 digits

answer: b.

step-by-step explanation:

it is b. cause the equations are put in the right category

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

the answer is: -22 also a

hope i
