great so whats the height of the cylinder...?

height=12?

campbell_st · Answer

great... so the area is the circular base  can be found by using the formula 

$$A = 3.14 \times r^2$$

just substitute you radius and calculate. 

when you have the answer, just multiply by the height of the cylinder.
