The age of sudha was 5/2 times as old as her younger sister sumi in 2055 b. s. and the age of sudha will be 10 years less than twice the age of sumi in 2070 b. s. find the birth year of sumi.

The graph of g(x) is a translation of y = which equation represents g(x)?

What is the value of x in the equation7x+2y=48 when y=3

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)
