How many radii does a sphere have?

one, if its a perfect sphere the radius will be constant whereever you measure it


How you find the radius of a sphere?

It depends on the information you have. You could put the sphere on a flat surface and lower a horizontal plane onto it so that it just touches the top of the sphere. The distance between the flat surface and the horizontal plane is the sphere's diameter; the radius is half that. Or you could measure its volume by measuring the amount of fluid (water) that it displaces in a measuring container or the overflow from any full container. Then use the formula V = 4/3*pi*R3 to work out the radius. If you knew the density of the material of the sphere, you could measure its mass and work out its volume that way.


Is a sphere 360 degrees?

We can't say how many degrees there are in a sphere, any more than we can say how many feet there are in an acre. Feet are a measure of length, and an acre is an area, not a length. You can't measure an area with a tape measure. Likewise, degrees are a measure of an angle; you can sweep out a circle by swinging a line through an angle of 360 degrees. But you can't sweep out a sphere by swinging a line through some angle, so angle measure won't do to measure a sphere.


How do you find the density of a sphere?

calculate the volume using the formula: Vsphere = (4/3)*pi*r^3 then calculate density by Density = Mass/Volume


How do you calculate the cubic feet of inside of a sphere sphere?

measure the radius of the sphere and apply the appropriate volume equation: V= (4/3) x (pi) x r3
