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

what are the answear choices to the question.

step-by-step explanation:

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
