The diameter of a wrecking ball used to tear down buildings is 3.5 ft. what is the volume ( to the nearest hundredth)

A wrecking ball is basically a sphere. So, to solve this problem we are going to use the volume formula for a sphere: 
where 
is the radius of the sphere 

We know for our problem that the diameter of the wrecking ball is 3.5 ft, so . To find its radius, we'll use the formula :



Now we can replace the radius in our formula to find the volume of our wrecking ball:




We can conclude that the volume of our wrecking ball is 22.45 .
