In the three dimensional geometry, a sphere is a shape that maintains a constant distance from a fixed point (center). This constant distance between the center of the sphere and the surface of the sphere is called the radius of the sphere. ...
Volume of a sphere formulaGiven the radius, the volume can be found by using the following formula: V = (4/3)pir3 = (4/3)πr3 pi or π is a special mathematical constant, and it is approximately equal to 22/7 or 3.14. If r or the radius of the sphere is known, the volume ...
2 The volume, V, of a sphere of radius r is given by=4/3πr^3 The radius, rcm, of a sphere is increasing at the rate of 0.5 cms-1. Find, in terms of t, the rate of change of the volume of the sphere when r = 0.25.4 ...
Volume of a Sphere by Integration: The formula for the volume of the sphere is as follows : {eq}\displaystyle V=\frac {4}{3} \pi r^3 {/eq} The sum of the cylindrical elements from 0 to radius r is a hemisphere. When we twice the hemisphere, we will get t...
Example 1: Find the volume of a sphere of radius 8 inches. Solution: The given radius of the sphere is r=8 inches. \( V=\frac{4}{3} \pi r^3 \) [write the formula for volume] \( =\frac{4}{3} \pi (8)^3 \) [substitute for r] ...
The volume of a sphere is found by using the formula 43π r^3 where r is the radius. In this case, the radius is 4 miles, so the volume is (256)3π cubic miles. This is equal to the volume of a cylinder of radius 8 miles so (256)3π=π8^2h, since the volume of a ...
