What is a reasonable slope of the line of best fit of the salary data for teachers in a New York
school district, as shown in the table below?

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)

Which angle has the same measure as the dehedral angle formed by the orange face and the purple rectangle

Suppose that circtes a and b have a central angle measuring 100. additionally, the measure of the sector for circle a is 10 m2 and for circle b is 40 m2 if the radius of circle a is 6 m, what is the radius of circle b?
