Ping me when if answering

Pls

@narrow shale Start from the fact that the two cylinders r similar which means the dimensions of the one are proportional to the dimensions of the other with ratio λ. Basically the dimensions that define a cylinder are its height h and its base radius r. Since the two cylinders are similar hA/hB=rA/rB=λ.

You know that the (Area of the base of A)= πrA^2 and the (Area of the base of B)=πrB^2 therefore πrA^2/πrB^2=9/25 => (rA/rB)^2=9/25. Use this to find the ratio λ.

Lemme try

I don’t get it @turbid briar

[turbid briar]

@narrow shale what you don't get?

[narrow shale]

I wrote out what you said it I have no idea

[turbid briar]

Do you understand what hA, hB, rA, rB represent?

[narrow shale]

The height of a.

The height of b

Radius of a

Radius of b

[turbid briar]

Ok so then what is λ

[narrow shale]

I don’t know

[turbid briar]

λ is the ratio between the two cylinders. For example in the case where λ is 2 you can say that cylinder A is two times bigger than cylinder B. This means that the height of cylinder A is two times the height of B and that the radius of A is two times bigger than the radius of B.

Ight Kk

[turbid briar]

Im sorry, i know i could just give you the answer but that way you won't learn anything.

[narrow shale]

Ye thank you for that

You’re a real one

[narrow shale]

@turbid briar ye I’m just stuck

Don’t get it whatsoever
