A student is using the Gizmo to estimate the area under the curve for f(x)=−x2+2x+3, between x=0 and x=1. The left-hand and right-hand sums are shown here. Which could be the actual area under the curve for that interval? A. 0.033 units2
B. 3.65 units2
C. 3.67 units2
D. 7.333 units2

Which segments are congruent? o jn and ln o jn and nm o in and nk onk and nm

For every corresponding pair of cross sections, the area of the cross section of a sphere with radius r is equal to the area of the cross section of a cylinder with radius and height 2r minus the volume of two cones, each with a radius and height of r. a cross section of the sphere is and a cross section of the cylinder minus the cones, taken parallel to the base of cylinder, is the volume of the cylinder with radius r and height 2r is and the volume of each cone with radius r and height r is 1/3 pie r^3. so the volume of the cylinder minus the two cones is therefore, the volume of the cylinder is 4/3pie r^3 by cavalieri's principle. (fill in options are: r/2- r- 2r- an annulus- a circle -1/3pier^3- 2/3pier^3- 4/3pier^3- 5/3pier^3- 2pier^3- 4pier^3)
