The unknown is the can's height.
The known and givens are diameter=8cm and π=22/7and volume is 804cm³
the formula is V/1/4πd²=h where d is diameter,V is volume and h is height
804/(1/4*22/7*8*8)=15.98 or 16(rounded to nearest hundredth or ones)
Therefore the can's height is about 16 cm. So it is taller than 15cm
