The formula for the surface area of a sphere is 4πr2.
The formula for the volume of a sphere is 4/3πr3.
Working out areas and volumes of circles and spheres respectively
The relationship between the surface areas of cylinders, cones, and spheres is that the surface area of a cylinder is equal to the sum of the areas of its two circular bases and its curved surface area, the surface area of a cone is equal to the sum of the area of its circular base and its curved surface area, and the surface area of a sphere is equal to four times the area of its circular base.

The total volume of the new sphere will be 4 times less than the sum of all eight individual volumes. The total surface area will be about half than the total surface area of all individual balls.
If the cells are spherical, the surface area increases as the square of the radius while the volume increases as the cube of the radius. Therefore, as the cells become larger, their volumes increase much more rapidly than their surface areas. Conversely, as the cells become smaller, their volumes decrease much more rapidly that their areas and so the surface area to volume increase. With non-spherical cells the calculations are much more complex, but the general pattern still applies.

Two spheres that are congruent are the same size and shape. Therefore, they would have the same surface area. So this statement is always true.
The relationship between the surface areas of cylinders, cones, and spheres is that the surface area of a cylinder is equal to the sum of the areas of its two circular bases and its curved surface area, the surface area of a cone is equal to the sum of the area of its circular base and its curved surface area, and the surface area of a sphere is equal to four times the area of its circular base.
The answer to the question depends on whether you want to calculate the surface areas or the volumes, or some other measure.
Volume of a sphere of radius r: V = 4pi/3 x r3 If the ratio of the radii of two spheres is 23,then the ratio of their volumes will be 233 = 1,2167
If the ratio is 2 : 7 then the volumes are in the ratio 8 : 343.
Volumes are storage areas, such as partitions and disks.

There are different formulae for their surface areas, volumes, lengths of sides as well as for the numbers of faces, edges and vertices.
It is 8 : 343.

Well, the formula for the surface area for one sphere is 4∏r2So if you have two identical spheres, the formula for the surface area of both would be 8∏r2
