No, it rarely is.
The volume of a sphere with a 10 in radius is: 4,188.8 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.
The volume of a sphere with a radius of 1 inch is about 4.2 cubic inches.
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

22.564 square inches (rounded)
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.
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 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.
