HALP A stack of 500 pieces of paper is 1.875 inches tall.

Diego guesses that each piece of paper is 0.015 inches thick. Explain how you know that Diego's answer is not correct.

F(n + 1) = f(n) – 8. if f(1) = 100, what is f(6)?

Which expression do you get when you eliminate the negative exponents of 4a^2 b^216a^-3 b

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)
