In Java,

The examples are exactly that examples, the code should make it so the inputs and outputs match.

The shape of a bottle is approximated by two cylinders of radius r1 and r2 and heights h1 and h2, joined by a cone section of height h3. Using the formulas for the volume of a cylinder, V= r2h, and a cone section, V=3(r12+r1r2+r22)h, Write a program to compute the volume of the bottle, given r1,r2,h1,h2 and h3 Example1: Input: r1=5.6,r2=2.3,h1=12.3,h2=3.0,h3=3.6 Output: The volume of the cylinder is 1447.65 cubic cm. Example 2: Input: r1=6.5,r2=3.2,h1=10,h2=4,h3=5 Output: The volume of the cylinder is 1838.82 cubic cm. Example 3: Input: r1=10,r2=9.8,h1=21,h2=6.8,h3=9.75 Output: The volume of the cylinder is 11645.32 cubic cm
