Can someone please help me with this geometry problem?
A pitcher of water is cylindrical 13 inches tall and has a radius of 5 inches. A solid cylinder, half as big as the launcher and a radius of 2.5 inches is placed on the launcher. By what fraction is the amount of water that may contain small launcher?
In response, calculate the volume of each cylinder. Begin by the large jug of water. The formula for the volume of a cylinder is: V = π r ^ 2 h, where V is the volume, r is radius and h is the height. We use in our values: V = (π) ((5 ") ^ 2) (13") V = 325π ≈ 1021 in ^ 3 We're doing the same thing for the small cylinder. We know that height is half the previous height of the cylinder (so h = 13 / 2 inches), and the radius is given (r = 2.5 in) = V (π) ((2.5 inch) ^ 2) (13 / 2) V = 325π / 8 ≈ 128 in ^ 3 The question we are asked by what fraction of the capacity of the large cylinder is reduced if the cylinder is smaller placed inside. In other words, what fraction of the volume of the cylinder the greater the volume of the smaller bottle? We adopt a simple reason: (325π / 
/ (325π) = 1 / 8 Thus, the ability of the launcher is decreased by one eighth when the smaller cylinder is placed inside.
