Answer:
The length of BC is needed because it is the side opposite ∠A.
Step-by-step explanation:
Answer:
Purple line: 4
Red dashed line: 2
Blue line: 1/2
Step-by-step explanation:
The purple line is the steepest line, therefore it has the biggest constant of proportionality or slope. Since 4 is the biggest number among the others, we attribute it to the purple line (the one with the point C on it).
Think of it this way:

here
so 
The greater a is, the greater y is. So for any value of x, y will be become bigger and bigger if we increase the value of a.
Take for example this one:

Take
therefore
Now take
and take
therefore
When we increased this constant of proportionality, as you can see from 2 to 4, the value of y increase from 4 to 8.
Hope this is helpful. Think of it really carefully, and I'm sure you'll grasp the concept.

True the answer is correct
Answer:
a=2304cm^2
Step-by-step explanation:
radius = 24 cm
diameter (also length in this case) = 24 x 2
= 48
let a = area
a=lw
a=48 x 48
a=2304cm^2
