*** PLEASE HELP IM TIMED

a sphere and a cylinder have the same radius and height. the volume of the cylinder is 11 ft ^3

which equation gives the volume of the sphere?


​

Answer 1

Archimedes solved this in his famous book Sphere and Cylinder in 225 BC. The result is reportedly on his tombstone.

The ratio of the volume of the radius r sphere to the cylinder radius r, height 2r is

`\frac 2 3`

The same ratio is the ratio of the surface area of the sphere to that of the cylinder (including the ends).

Answer: Last choice

Answer 2

The first one because it’s the actual formula for a sphere and it has pie at the end because we are solving for a sphere
