Volume of a cylinder = πr²h
V= 3.14159 × (3)² × 7
V= 197.92 ft³
I'm quite sure this is impossible to prove, because the volume of a sphere is not equal to the volume of a cylinder with the same radius and height equal to the sphere's diameter. This can be shown as: Volume of sphere = (4*pi*r3) / 3. Volume of cylinder = pi*r2*h. Here, the height, h, of the cylinder = d = 2r. So, the volume of the cylinder = pi*r2*2r = 2*pi*r3, which obviously does not equal the volume of the sphere. The volume of half a sphere (with radius r) is equal to the volume of a cylinder(whose height is equal to its radius, r) minus the volume of a cone with the same height and radius. Therefore, the volume of a sphere is just double that. If you follow the nearby link, you can see a nice demonstration of that.
The curved surface area of a cylinder whose height is 14 feet and radius is 6 feet is 527.79ft2
754 square feet.
The formular for the surface area of a cylinder is 2(pi)rh + 2(pi)r2 where r=radius and h=height and pi=3.14 SA= 2 x 3.14 x 15 x 30 + 2 x 3.14 x 152 =4239
The volume of this cone is 37,699 cm3
The volume of a cylinder whose radius is 3 and height is 6 is: 169.6 units3
A cylinder with a radius of 3 feet and a height of 3 feet has a volume of 84.82 cubic feet.
