Need help explaining Study Island question

Answer 1

Sorry guys.. I'm "that annoying study island person" lol

Answer 2

Any ideas?

Answer 3

Have no clue. How can I dilate it using the scale factor when it's a circle?

Answer 4

Good question. Think about what the word "dilate" means...

Answer 5

Make bigger? if I can find one pair of coordinates and multiply them by 3 will that help a little?

Answer 6

So you want to make the ENTIRE circle bigger, right?

Answer 7

Maybe : ) Is that what I need to do

Answer 8

Yeah make the entire circle bigger and THEN find the radius of the new image, I don't know where to start though

Answer 9

OH I SEE IT :DD The radius is half diameter. On the graph, the diameter is 7, half of 7 is 3.5 So find 3.5 on the graph in the center of the circle. 3.5 x 3 is 10.5 and one answer choice is 10 1/2 units which simplifies to 10.5 so that's the answer

Answer 10

Correct.

Answer 11

Thank you for the help!
