PLEASE HELP I WILL GIVE A MEDAL AND FAN Sergio has two similar cylindrical pots, Pot A and Pot B. The radius of Pot A is 15 inches, and the radius of Pot B is 3 inches. What is the ratio of the volume of Pot A to the volume of Pot B?

OpenStudy (helpkay):

do you have a picture BTW I am not good with this at all

OpenStudy (emsxx3_):

they didn't give a picture

OpenStudy (emsxx3_):

would it be area measure is a^2:b^2 volume measure is a^3:b^3

OpenStudy (jadeishere):

Would you explain how you got that :) @emsxx3_

OpenStudy (emsxx3_):

since the radius went from 18 to 13 the radius decreased by a factor of 13/18 then the new hight decreased as well by 13/18 so they want the ratio of pot a to pot b so V1:V2 so then i did 18^2:13^3/18 so h/18=x/3 solving for x gives 3/18 and then i got area measure a^2:b^2 volume measure is a^3:b^3

OpenStudy (jadeishere):

Where'd the 13 and 18 come from?

OpenStudy (emsxx3_):

the figure i drew i would attach it but it won't let me

OpenStudy (jadeishere):

Well, I'm sorry to say, but that is incorrect :( Would you like me to walk you through the question?

OpenStudy (emsxx3_):

yes please

Kay :) Sergio has two similar cylindrical pots, Pot A and Pot B. The radius of Pot A is 15 inches, and the radius of Pot B is 3 inches. What is the ratio of the volume of Pot A to the volume of Pot B? (I just copied it.. Haha xD) |dw:1469208659672:dw| So far, the ratio is 15:3 (in inches, not squared or cubed) simplified to 5:1 When a person is looking for volume, is it usually in; in (line) in^2 (squared) in^3 (cubed)
