a 48 inch long cylindrical shaped cannon has a diameter of 4 inches. there are two 3 inch diameter cannonballs inside it. how much empty space is in the cannon barrel (round to the nearest hundredth and use 3.14 for pi)?

Step-by-step explanation:

First we calculate the volume of the cylinder.

Where r is the radius and l is the length of the cylinder.

We know that:

Then:

Assuming that the cannon balls are spherical then the volume of the 2 spheres is:

So the space left inside the cannon is

step-by-step explanation:

consider an orange peel: if you want to try and lay it flat, you have to stretch it, we know exactly how things are being stretched or squashed at any given point. we have many different map projections because each has different patterns of some projections can even preserve certain features of the earth without
