The formula for a sphere is derived from the formula for a cone. A sphere is twice the size of a cone with the same radius. The volume of a cone is 1/3*pi*r squared.* h. In a cone, h is the height; in a sphere, the height is the diameter, which is 2r. Therefore, the...
volume of the sphere (v) = 4/3 π r 3 v = 4/3 x 3.14 x 6 3 v = 4/3 x 3.14 x 6 x 6 x 6 v = 904.32 hence the volume of the sphere is 904.32 m 3 . example 2 : a plane passes through the centre of a sphere and forms a circle with a radius of 12 feet. ...
Volume = (100.48)/(81) Volume = 1.24 in.3 Volume of a hollow sphereSuppose a sphere with an inner radius r is removed from a sphere with an outer radius R. What you end up with is called a hollow sphere or a sphere that has a cavity inside of it. In the figure below, the ...
1 Volume:The radius r of a sphere is increasing at a rate of 2 inches per minuteFind the rate of change of the volume when r=6 inches and r=24 inchesExplain why the rate of change of the volume of the sphere is not constant even though dr/dt is constant 2 Volume:The radius r...
Finding the diameter from the radius is very simple. As you can see, the diameter is twice the radius. If you have the volume of a liquid sphere, and you need to calculate the diameter, then it is a simple matter of multiplying the radius by 2....
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 ...
