Answer 1

Explanation:

The Radius is (1/2) of the diameter, so to get the diameter we will multiply the radius by 2.

1. 9*2=18in

The we multiply the diameter by
`\pi` to get the cicumference. We know to do this because the equation of the circumference is C=
`\pi`d or C=2
`\pi`r. (p.s
`\pi`=3.1415926)

2. 18in*(3.1415926)=56.5487in

3. If the diameter is doubled the circumference is also doubled. We know this because of the equation C=
`\pi`d. The circumference is dependant upon the diameter and grows (or shrinks) with it.

Answer 2

See below

Explanation:

If the diameter is doubled, the circumference is doubled. It is shown here:

18 * 3.14 = 56.52

36 (doubled diameter) * 3.14 = 113.04

If the circumference with the doubled diameter divided by the circumference of the original diameter comes out as 2, then it is proven that doubling the diameter doubles the circumference.

113.04/56.52 = 2.
