Radius is 15 cm
Circumference = 2 pi r
C = 2 x 3.14 x 15cm
C = 94.2 cm
94.2 cm x 4 (revolutions) = 376.8 = D
Answer:
Figures can be proven similar if one, or more, similarity transformations (reflections, translations, rotations, dilations) can be found that map one figure onto another. In our attempt to prove all circles are similar, a translation and a scale factor (from a dilation) will be found to map one circle onto another.

Answer:
I recommend using a graph that can help. For slope afind two solid points and make it a fraction. Y intercept is where it passes through the y axis.
Step-by-step explanation:
Answer:
x = 0.447
Step-by-step explanation:
You need to use your graphing calculator for this.
In y=, put 13(0.25)^x in Y1 and put 7 in y2. Using 2nd trace, find the intersections.
The answer I got was x = 0.447.
