Step-by-step explanation:
We have been given that a label wraps around soup can with a radius of 4.3 cm and a height of 6 cm. We are asked to find the lateral surface area of the label of the soup can in square centimeters.
We will use lateral surface area of cylinder to solve our given problem as:
, where,
r = Radius of cylinder,
h = height of cylinder.
Upon substituting our given values in above formula, we will get:



Therefore, the lateral surface area of the label of the soup is approximately 162.11 square cm.
It is $0.05 per ounce, so at that rate, a 128 oz container would cost $6.40.
