Question

A company is going to make an oil container in the shape of a cylinder. As shown below, the container will have a height of 8 m and a radius of 6 m The container will be made from steel (including its top and bottom). Suppose the total cost of the steel will be 17,408.16 How much will the steel cost per square meter? Use for 3.14 and do not round your answer.

Answer 1

Explanation:

Total surface area of a cylinder =

Area of curved surface (the round body) + area of two circular covers ( the top and bottom cover)

= 2πrh + 2πr²

= 2πr(h+r)

= 2 • 3.14• 6•(8+6)

= 527.52 m²

Cost per m²

= 17,408.16/527.52

= £33
