The radius of circle M is 3 times the radius of circle P. If the area of circle P is abotu 27 sq. cm. the area of circle M is about what? (Use 3 as pie) i don't get it. is the scale ratio 3:1?

Whoa. Use 3 as Pie?
yeah. that's what the ? says to use
i thought the scale ratio would be 3:1 because of the fact that the question says that the bigger circle is 3 times as big as the little one
it the radius of M is 3x the radius of P, then the area is 9x (remember area is proportional to radius squared).
So, if P is 27, then M is 27*9
So, if P is 27, then M is 27*9
Hmm.. Since the radius is 3 times larger than P, its diameter should be 18. P's diameter should be 6.
That might help you solve the problem.

ok, but how would you get that into a proportion. i get the rest of the question, just not how to put those # into a scale ratio
hello anybody there? sorry it took so long to post a response, i was trying to figure it out
never mind i get it. Thanks for your help
