A can of tomatoes has a 4 in. diameter and is 4.5 in. high. What is the area of the paper label that goes around the can?
A) 14.1 in2
B) 28.2 in2
C) 56.5 in2
D) 81.6 in2
So to find the volume of a cylinder we must use the equation 2πrh+2πr^2. So when we input the numbers we get, 2π(2*4.5)+2π(2)^2. This gives us the answer 26 times pi, or 81.6814089933. So your answer is D.
