Will give brainliest 20 points rectangle abcd has coordinates a(-2,4), b(8,4), c(8,-6), and d(-2,-6) aiesha transforms the rectangle by using the rule (x, y)-> (x,1/2y), while gino transforms the rectangle by using the rule (x, y)-> (1/2x, 1/2y). which statement is true? a. the perimeter of gino's image is 2/3 the perimeter of aiesha's image. b. the perimeter of gino's image is 1/2 the perimeter of aiesha's image. c. the perimeter if gino's image is 1.5 times the perimeter of aiesha's image. d. the perimeter of gino's image is twice the perimeter of aiesha's image.

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)
