42.39 inches squared, or the first option
A can is shaped like a cylinder. So, to find the lateral area of the tin can we must follow the lateral area formula for a cylinder, or 2 • π • radius • height
You can simply substitute the values from here.
The question wants you to use 3.14 instead of π, so the formula becomes 2 • 3.14 • radius • height
The can's radius is 1.5 inches and its height is 4.5 inches, so the formula becomes 2 • 3.14 • 1.5 • 4.5
Now we just solve: 2 • 3.14 • 1.5 • 4.5 = 42.39, so the lateral area is 42.39 inches squared.
