A circle is sometimes/always/never

similar to another circle, because we can sometimes/always/never

map one onto the other using only dilations and rigid transformations.

A circle is always similar to another circle, because we can always map one onto the other using only dilations and rigid transformations.

Step-by-step explanation:

Two Circles are said to be similar if all the linear measurements of the circles are proportional.

Lets consider if  two circles have a certain ratio of their radii, , it definitely mean that  all the other corresponding ratios will also have that same ratio.

Concentric circles are defined as the  circles which have a  common center. The area between the  two concentric circles having  difference in their  radii is Known  as annulus.

The most important property of a circle is that all  points on the circle are equidistant (i.e. having the same distance) from the center point.

A circle is always similar to another circle, because we can always map one onto the other using only dilations and rigid transformations.

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value
