Samuel received $250 as prize money for winning the st. peterson high school badminton tournament. the money was deposited in a special scholarship account that offered an annual interest of 1.8% compounded semiannually. the amount he will have in the account after t years can be calculated using the expression below. use the given expression to complete the statements below. the expression is the of the amount initially deposited and the of one and the rate of increase raised to the number of .

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)
