Question

A new cylindrical can with a diameter of 7 cm is being designed by a local company. The surface area of the can is 150 square centimeters. What is the height of the​ can? Estimate using 3.14 for π , and round to the nearest hundredth. Apply the formula for surface area of a cylinder SA=2B+Ph

Answer 1

Explanation:

SA = 2πr (h+r)

150=2(3.14)(7/2)(h+(7/2))

150/(2(3.14)(7/2)) = h+(7/2)

6.82=h+(7/2)

h = 6.82-3.5 = 3.32
