No, it rarely is.
The volume of a sphere with a 10 in radius is: 4,188.8 cubic inches.
The volume of a sphere with a radius of 1 inch is about 4.2 cubic inches.
A sphere of radius 12 inches cannot have a height of 23 inches. It is, in that case, a flattened sphere and a lot more detailed information about the flattening is required to find its volume.
Fist you've got to find the volume of the sphere, if the radius was 4cm then it would be...4/3*pi*r3=268cm V of cylinder= pi*r2*l (the radius for example is 8cm) 268=pi*64*l L=268/64pi =1.3cm
Treat the 3D sphere as a 2D circle. The radius for the sphere is the same radius as for the circle. No matter where on the sphere you place a mark, the distance (radius) from the mark to the centre of the sphere will always be the same as the circle.
A sphere with a radius of 7 inches has a volume of 1,436.76 cubic inches.
A sphere with a radius of 3 inches has a volume of 113.1 cubic inches.
A cylinder with base radius r and height 2r. This cylinder circumscribes a sphere of radius r.
A sphere with a radius of 2.12 inches has a volume of 39.91 cubic inches which equates to 654.008mL

If the radius of the hemispheres is 4, then that leave 4 units for the length if the straight part of the cylinder. Total surface area = surface area of 1/2 sphere of radius 4 + lateral surface area of cylinder of radius 4 and height 4 + surface area of 1/2 sphere of radius 4. = surface area of sphere of radius 4 + lateral surface area of cylinder of radius 4 = 4*3*pi*43 + pi*42*4 = 469.1 cubic units.
A sphere with a radius of 30 inches has a diameter of 60 inches, a surface area of 4π(30 inches)^2 ≈ 11,310.7 square inches, and a volume of 4/3π(30 inches)^3 ≈ 113,097.3 cubic inches.
