Katelynn measures her bean plant on Monday and again on Friday. She says that her plant grew 10 quarter inches. Her partner records 2 1/2 inches on his growth chart for the week. Is her partner right? Why or why not?

What happens to the area as the sliders are adjusted? what do you think the formula for the area of a triangle is divided by 2?

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)

What is 10+10+20 about the origin the square root of a triangle.
