Answer:
The diameter is 2 times the radius.
D=2r
Substitute 20 as the diameter and solve for r.
20=2r
Divide both sides by 2.
10=r
So, the radius is 10 centimeters.

Answer:
y=4x
Step-by-step explanation:
The equation of a line is y=mx+b, where m is the slope and b is the y intercept.
The slope formula is Δy/Δx, so using the coordinates (1, 4) and (2, 8), the slope is
which equals 4.
The y intercept is 0.
Therefore, the equation is y=4x.
