Step-by-step explanation:
Formula For Cylinder: πr²h
Formula For Cone: πr²h/3
d = 2r, r = d/2
8/2 = 4. Both the cylinder and cone have a radius of 4 inches. Now let's plug that in for our equation.
Cylinder: 3.14 · 4²· 9
Cone: 3.14 · 4² · 18/3
Now let's simplfy
Cylinder: 452.16 in³
Cone: 301.44 in³
We can see that they both have a difference of 150.72
