A soup can has a diameter of 3 1 8 inches and a height of 5 1 4 inches. When you open the soup can, how far does the can opener travel? (Round your answer to one decimal place.)

Answer 1

This question is asking you to find the circumference of the top of the can. How far does the can opener have to travel? It has to travel all the way around the edge of the top of the can (circumference). How do we calculate the circumference?

2(pi)(radius)

or the diameter times pi

They gave us the diameter which is 3 1/8 inches

So, 3 1/8 x pi = 9.8 inches
