1. in δpqr, pq = pr and m is the midpoint of qr . prove that pm bisects ∠qpr. answer format: δpqm = δ (reason) 2. in δabc, m∠b = m∠c. the angle bisector of ∠b meets ac at point h and the angle bisector of ∠c meets ab at point k. prove that bh = ck. answer format: δbck = δ (reason) 3. in ∆abc the median am is extended to ray am and point p on am is taken so that pm = am. what is the distance from point p to vertices c and b if ab = c and ac = b?

Which rule describes the composition of transformations that maps △abc to △a”b”c

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)
