Which represents a perfect cube?
8 times 8 times 8
8 + 8 + 8
9 times 9 times 9 times 9
9 + 9 + 9 + 9 + 9

Anything to the third power is a perfect cube

Step-by-step explanation:

Ex 8^3 in this situation

It can also be written like 8.8.8

x.x.x is a perfect cube but x.y.z is not because they have different lengths.

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

b. 2 and 4
