Answer:
The radius is: 
Step-by-step explanation:
The equation of a circle in center-radius form is:
Where the center is at the point (h, k) and the radius is "r".
So, given the equation of the circle:
You can identify that:
Then, solving for "r", you get that the radius of this circle is:
Answer:
91.125 or 729/8
Step-by-step explanation:
take 4.5^3 to get 91.125
I believe it's 3 months because 12 divided by 4 is 3.
The scientist can use only the angle x and the distance y to calculate the distance between the Earth and the Sun using the cosine function.
cos x = BC / y
Solving for BC
BC = y cos x
BC is the distance between the Earth and the Sun :D
