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 7m and a radius of 6m . The container will be made from steel (including its top and bottom). Suppose the total cost of the steel will be $18,613.92. How much will the steel cost per square meter? Use 3.14 for pi , and do not round your answer.

Answer 1

Explanation:

For oil container in the shape of a cylinder

radius (r) = 6 m

height (h) = 7 m

TSA of Cylinder

= 2πr ( r + h)

= 2 * 3.14 * 6 ( 6 + 7)

= 2 * 3.14 * 6 (13)

= 2 * 3.14 * 6 * 13

= 489.84 square meter

Now,

the total cost of the steel will be $18,613.92.

= 18613.92/489.84

= $38

Thus, The TSA of a cylinder is 489.84 square meter and $38 will the steel cost per square meter.
