Question

Math help, please?

Answer 1

Prove that the two circles shown below are similar.

Circle X is shown with a center at negative 2, 8 and a radius of 6. Circle Y is shown with a center of 4, 2 and a radius of 3.

Answer 2

one method would be to show the ratio of the circumferences is the same as the ratio of the radii.

Answer 3

How would you do that?

Answer 4

Answer 5

use the ratio of larger to smaller

radii: 6:3 or 2:1

circumference \[2\times \pi \times 6: 2 \times \pi \times 3\]

simplify the ratio...

the method really depends on the topic you are studying...

but similar shapes have all measurements in the same ratio
