Question

anonymous · Answer

the height is 12 and a half centimeters and the width is 2 inches and the radius is 22 centimeters.

anonymous · Answer

2 times pi times the radius plus 2 times pi times the radius times the hieght.....

anonymous · Answer

(h is the height of the cylinder, r is the radius of the top) 

Surface Area = Areas of top and bottom +Area of the side 

Surface Area = 2(Area of top) + (perimeter of top)* height 

Surface Area = 2(pi r 2) + (2 pi r)* h

@hayhay5270  lool yup tht

anonymous · Answer

you need to convert to cm or inches and work with one unit before attempting this problem. i would work in cm since that is a smaller unit than inches so convert from inches to cm then plug into the formula that was posted by @hayhay5270  earlier
