    Remember

    area=pir^2

    circumference=2pir

    the surface aera if you thinkg about it is

    2 times the tops+area around

    the tops are circles so 2*pir^2 is tops

    the area around is a rectangle that has been wrapped around the cylinder,

    the hieght is the legnth and the circumference is width

    so 2hpir is the area around

    2pir^2 is the areas of the tops

    2hpir is the area around
