volume  =  area of base * height

 

volume  =  pi * radius2 * height            radius  =  12/2  and  height = 10

 

volume  =  pi * (12/2)2 * 10

 

volume  =  pi * 62 * 10   =   pi * 36 * 10   =   360pi  in3   ≈   1130.973  in3

 

 

surface area  =  circumference of base * height  +  2 * area of base

 

surface area  =  pi * diameter *height  +  2 * pi * radius2

 

surface area  =  pi * 12 * 10  +  2 * pi * 62

 

surface area  =  120pi  +  2 * pi * 36

 

surface area  =  120pi + 72pi   =   192pi   in2   ≈   603.186  in2
