First, you need to multiply 2*21cm, which gives us 42 cm.

Then we multiply it by π, or 22/7 in this case, and 22/7*42cm gives us 132 cm.

So the answer is: 132cm.

Hope this helped! c:

Lunna [17]

Answer:

The increase is 9.1%

<u>Step 1:  Make an equation </u>

66 * x = 72

66x = 72

66x / 66 = 72 / 66

x = 1.09090

X/-9 =3<br>I dont understand this.​
STatiana [176]

Final Answer: x = -27

Steps/Equations:

Question: \frac{x}{-9} = 3

Step 1: Move the negative sign to the left side.

-\frac{x}{9} = 3

Step 2: Multiply both sides by 3.

-x = 3 * 9

Step 3: Simplify 3 * 9 to 27.

-x = 27

Step 4: Multiply both sides by -1.

x = -27
