trapezoidal rule (1 Viewer)

[Arithela]

1. A cone is generated by rotating the line y = 2x about the x-axis between x = 0 and x = 3. Using trapezoidal rule with four function values, estimate the volume of the cone.

how do we find the volume with this rule??

Get the corresponding y values, then square them. THEN you plug it into the formula.
