2.83941151 would be the answer you're looking for! : )

1.3 million hoops i believe

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!

why are you giving so many marks make your marks less and make a question list so that i can understand your question very nicely
