If the circumference is 100 cm, then to get the diameter you need to divide by pi.
So...
100cm = pi × diameter
100/pi = diameter
diameter = <span>3062.77772486 cm</span>

Answer:

31.85cm

Step-by-step explanation:

Taking the figure in question to be a circular figure.

Formula for finding the circumference of a circle is expressed as:

C = πd where d is the diameter of the circle.

The distance around the figure will serve as the diameter of the figure.

Given circumference = 100cm and π = 3.14

100 = 3.14d

d = 100/3.14

d = 31.85cm

The distance around the figure is 31.85cm

22. Solve 7x - 9 = 28+ 4(x - 1).<br> X=-3<br> X=3<br> x = 11<br> X=-11​
aleksley [76]

Answer:

c) x = 11

Step-by-step explanation:

Given equation: 7x - 9 = 28 + 4(x - 1)

<u><em>Steps:</em></u>

1. Distribute 4 through the parentheses:

7x - 9 = 28 + 4(x) + 4(-1)

7x - 9 = 28 + 4x - 4 [simplify]

7x - 9 = 24 + 4x

2. Subtract 4x from both sides:

7x - 4x - 9 = 24 + 4x - 4x

3x - 9 = 24

3. Add 9 to both sides:

3x - 9 + 9 = 24 + 9

3x = 33

4. Divide both sides by 3:

3x ÷ 3 = 33 ÷ 3

x = 11

5. Check your work:

7x - 9 = 28 + 4(x - 1) [substitute 11 for x]

7(11) - 9 = 28 + 4(11 - 1) [simplify]

77 - 9 = 28 + 4(10) [simplify]

68 = 28 + 40 [add]

68 = 68 ✔
