I can answer virtually any kind of question dealing with of Math 536 and below, my forte being in parabolic functions and analytical geometry. I'm currently learning Calculus I, and cannot answer questions that deal with subject matter more advanced than that.

Experience
I am neither a professor nor a teacher of this subject. I am merely a student who is gifted at mathematics and enjoys being of service to his community. I frequently tutor people in math and the results are usually great.

Subject: Similarity - Calculating Scale Factor

Question
if the height of a cone is tripled and the radius is doubled, then the volume of the new cone is how many times the volume of the original cone?

Answer
Hey Meilani!

For the initial cone, let all the parameters equal 1.  Put the scale factor, k, on this side of the equation.  On the other side, put the cone with the new parameters.
(πhr^2)k=πhr^2
((1)(1)^2)k=(3)(2)^2
k=(3)(4)
k=12

SOLUTION: The volume of the new cone will be 12 times that of the original.

Glad to help,
Azeem
