Transcribed Image Text:Write a Riemann sum for the volume, using the strip shown and the variable y:
Riemann sum = Σ
Consider the volume of the region shown below, which shows a right circular cone with top radius 3 cm and height 9 cm. We have used the notation Dy for Ay.
Now write the integral that gives this volume:
volume = f
where a =
and b
=
. E.g. "pi (5x +3) Dx" or " pi (y^2) Dy"
. E.g. "(5 pi x +3) dx" or "(pi y^2) dy"
Finally, calculate the exact volume of the region, using your integral.
volume =
(include units)
Dy
