Answer:
The value of radius is 7.5 units
Step-by-step explanation:
Given that a line that pass through the origin and form a triangle is a right-angle triangle. So in order to find the diameter/hypotenuse, you have to use Pythogaras Theorem :

Let a = 12 units,
Let b = 9 units,
Let c = hypo.,




We have found out that the hypotenuse of the triangle is the diameter of circle. So in order to find radius, you have to divide it by 2 :



Answer:
12

Answer:
$299
Step-by-step explanation:
Make a proportion
He makes $184 for 8 hours of work, and $x for 13 hours of work
184/8=x/13
To solve, we need to get x by itself. To do this, multiply both sides by 13. We multiply because x is being divide by 13, and we want to do the opposite.
13(184/8)=(x/13)13
The 13s on the right will cancel, leaving us with
13(23)=x
299=x
So, he will earn $299 for 13 hours of work.
