Answer:
Standard form of

Step-by-step explanation:
Here, the given expression is 
Now, simplifying the above expression in parts, we get

hence, combining both parts:


= 
The above expression is of the STANDARD FORM: 
Hence, the standard form of

(1/3) of (14-1/3) = (1/3) x (43/3) = (43/9) = about <em>(4 and 7/9) gallons</em>.
D. 28
this is because 48 divided by 12 is 4, 4 times 7 is 28.
They forget to say "not to scale". I'm guessing this is trig because I don't see another way to do it.
Let's consider x=chord PQ first. By the Law of Cosines

We have an isosceles triangle formed by two radii of 9 cm and x=PQ. By the Law of Cosines again,





The area of the circle is the fraction given by the angle,
