This figure is 1/4 of a circle.
drek231 [11]

For this case we have that by definition, the perimeter of a circle is given by:

C = 2 \pi * r

Where:

r: It is the radius of the circle.

According to the figure, it is observed that the radius of the circle is 2. Then:

C = 2 \pi * 2\\C = 2 * 3.14 * 2\\C = 12.56 \ in

Let's remember that we have a quarter circle:

C = \frac {12.56} {4}\\C = 3.14

We round and we have that the correct option is 3.1 \ in

Answer:

Option A

The attached figure is the image that completes the question

Annie says the two expressions are equalized. Is she correct? Explain using different strategies -3x+6 and 3(-x -2).
borishaifa [10]

Step-by-step explanation:

By using Distributive Property on 3(-x - 2),

3(-x - 2) = (3)(-x) + (3)(-2) = -3x - 6.

Since -3x - 6 =/= -3x + 6,

they are not equalized.

Whats 2x2+34x24+3x0+1x400x100x456x0
aivan3 [116]

Answer:

820

Step-by-step explanation:

If you use order of operations, you can find that 3x0 and 1x400x100x456x0 is just 0 so you just have to add 2x2 and 34x24. Which is 820

order of operations is

GEMDAS

Grouping symbols

exponents

multiplication and division (these don't have to be in order)

Addition and Subtraction (again, these don't have to be in order)
