The volume of a sphere whose radius is 9 meters is: 3,054 meters3
(4/3)*pi The formula for the volume of a sphere is (4/3)*pi*radius3
V = 268.1 cubic feet.
V = 4/3*pi*r^3 you do the math
In order to find the surface area we must first find the radius of the sphere:- Volume of the sphere = 4/3*pi*radius3 = 113.1 cubic inches Multiply both sides by 3: 4*pi*radius3 = 339.3 Divide both sides by 4*pi: radius3 = 27.0006361 Cube root both sides: radius = 3.000033559 Surface area of the sphere = 4*pi*3.0000235592 = 113.0991118 square inches

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.
