Question

A triangle formed by the x-axis, y-axis and the line y = ax + b, if a = -b then what is the volume of the cone generated by rotating the triangle around y-axis?

Answer 1

the answer is pi/3 a @Hezum

Answer 2

Ok thanks rose, but how? can you tell me the solution?

Answer 3

Or if you can attach here the screenshot.

Answer 4

the height is b as him said - the intercept on the x axis is -b1/2
so the volume is (1/3) pi r^2 h
= (1/3) pi 1^2 * -b
=(1/3)* pi * a
= (pi/3) * a which is b) on the list
