Answer:

70.69 or 22.5 pi

Step-by-step explanation:

To find the circumference of a circle, you can use the formula:

2 x pi x radius

Using this formula, we can substitute the information that we already know, and solve for the circumference:

2 x pi x 45/4

6.28 x 45/4

70.69 or 22.5 pi

Answer:

22.5π units² or about 70.65 units²

Step-by-step explanation:

11 \frac{1}{4} is equivalent to 11.25

The formula for the circumference of a circle is 2πr. Using that formula we get:

2*π*11.25 = 22.5π ≈ 70.65

Please help , I really need it thanks!

The symbol "<=" without quotes means "less than or equal to"

-6x + 2y <= 42
-6x + 2y + 6x <= 42 + 6x ... Add 6x to both sides
2y <= 6x + 42
2y/2 <= 6x/2 + 42/2 ... divide every term by 2
y <= 3x + 21

So the answer is choice D
