Answer:
22 in
Step-by-step explanation:
<u>circumference of a circle = 2 π r</u>
where radius (r) = 7/2 in. = 3.5 in
C = 2 π (3.5)
= 22 in
Since the area of a circle is π

, and our radius is 9 we know the total area to be 254.469, and the ratio of sector area to total area is 169.56/254.469 = .6663. There are 360 degrees in a circle, so:

≈ 240°
240 degrees
The answer to the problem is approximately 19 liters
The logarithm of a quotient can be written as a difference of logarithms:

You can also think of this as a combination of the product-to-sum and reciprocal/power properties of logarithms:

To summarize,



The answer is B, I'm on the test now.
