Volume- Sphere, Cone, Cylinder

Volume- Sphere, Cone, Cylinder

Applying the volume formula

I need volume...

Write out the equation.
Look at the directions - are you using 3.14 or $\pi$  

Do you have the radius or diameter? If you have diameter what should you do first?
Make sure that you square or cube the radius

I have the volume...

How is the volume written? Do you se pi?
If you have  $\pi$  then you should use it when you write your equation.  

You will divide your volume by pi, the fraction (if cone/sphere), and the other value given. 

If you are finding radius don't forget to  $\sqrt{r^2}$  or   $3_{\sqrt{r^3}}$  

Relationships...

How are cones related to cylinders? How does the formula change?

How are spheres different from cylinders? How is the formula different?

Can we compare cones and spheres?
