Consider the volume of the region shown below, which shows a right circular cone with top radius 2 cm and height 7 cm. We have used the notation Dy for Ay. Write a Riemann sum for the volume, using the strip shown and the variable y: Riemann sum = Now write the integral that gives this volume: volume = f where a = and b = Y Finally, calculate the exact volume of the region, using your integral. volume = (include units) Note: You can earn partial credit on this problem. E.g. "pi (5x +3) Dx" or " pi (y^2) Dy" . E.g. "(5 pi x +3) dx" or "(pi y^2) dy"
