Ineed the answers for a1 to a4 cause i don’t understand it

A1 There are two ends so their combined surface area is 2 π * r2. The surface area of the side is the circumference times the height or 2 π * r * h, where r is the radius and h is the height of the side. The entire formula for the surface area of a cylinder is 2 π r2 + 2 π r h. so add the number of the height and radius plug in and you will get the answer for that.

Just a question- could you organize the data better? i just cannot tell which number are for which bakery. i will be happy to answer this question if you could do this for me! : )
