Step-by-step explanation:
I don't see question 1 and 2.
but it did be way for you : the distance from the verge of a circle to a point on the circle is always the radius.
that is the whole concept of a circle : it is the line (or curve) of all points that have the same, constant distance r from a single point.
Answer:
<em>r=6</em>
Step-by-step explanation:
<u>Proportions
</u>
We know M is directly proportional to 
This can be written as
Where k is the constant of proportionality which will be determined knowing that when r = 4, M= 160. Substituting in the equation above:
Solving for k:
The equation is:
Now find r when M=540:
Dividing by 2.5:
Taking cube roots:
![r=\sqrt[3]{216}](https://tex.z-dn.net/?f=r%3D%5Csqrt%5B3%5D%7B216%7D)
r=6
Answer:
60.6°
Step-by-step explanation:
Tan ACB = opp/adj
= 10.3/5.8
ACB = 60.61584287 = 60.6

Hello!
Dwayne would've had 50 total questions on the test if he got an 80% with 40 correct answers. (40/50 = .8, .8 x 100 = 80)
Hope this helped and good luck!
