Question

a Can of soup has a diameter of 2.5 inches and a height of 4 inches. how much metal is needed to make the can? round your answer to the nearest tenth.

Answer 1

First the 2 bases have surface area pi*1.25^2*2

Then the side

2.5pi*4=10pi

total of 9.817+31.415

=41.232

This approximation could be further round down for this problem to 41.2

Which makes choice C the correct choice.
