A package of 12 pencils cost $0.96. At this rate, how much would 100 pencils cost?

$8.64

Step-by-step explanation:

.96 per every 12 pencils, so 8 times 12 is 96 and an addition 4 pencils would result in a fourth of the .96 being . 24, however that isnt logical so you would have to use the next number being 9 packs for 108 pencils

step-by-step explanation:

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
