A Can of Volume!
Step by step...
Cylinders and their circular bases.
Since cylinders have circular bases, they use the equation -Area equals Pi times Radius Sqared. Lets look at the dimensions of the figure: Hight=12 Length (Diameter)=6. Now the equation states radius sqared, the radius times itself. The radius is half the diameter so 6 halfed is 3. 3x3=9. The next part of the equation is multiply the sqaured radius by Pi. Pi is usually 3.14 units. when multiplying 9x3.14, make sure you put the decimal in the correct spot. 28.26 will be your awnser. Take 28.26 and multiply that by the hieght, 12 and get 339.12 cubic units!
