C = 2πr
c/2π = 2πr/2π <--divide both sides by 2π
c/2π = r
r = c/2π <-- answer :)
First question
1:C 2:D 3:B 4:D
second question
0-2+5
Answer:
2:1
Step-by-step explanation:
Circle P has radius 14 feet.
The circumference of this circle is given by:

We plug in the radius to get:

Circle Q has diameter 14 feet.
The circumference of this circle is given by

We substitute the diameter d=14 to get,


The ratio of the circumference of P to the circumference of Q is

Answer:
The slope is 3/2, and the y-intercept (b) is -1
Step-by-step explanation:
The slope-intercept form is y=mx+b. m is the slope and b is the y-intercept.
