Answer:
332 cm²
Explanation:
You want to know the surface area of a tin can that is 7 cm in diameter and 11.6 cm high.
Surface area
The area of a cylinder is given by the formula ...
SA = πd(d/2 +h) . . . . . where d is the diameter and h is the height
Application
Using the given values, d=7 and h=11.6, we find the area to be ...
SA = (3.14)(7 cm)(3.5 +11.6 cm) ≈ 332 cm²
About 332 square centimeters of tin are required to make the can.
