An observer standing on a cliff 320 feet above the ocean measured angles of depression of the near and far sides of an island to
Gnesinka [82]

Answer:

154.10 Feets

Step-by-step explanation:

Given the following :

Height (h) of cliff = 320 feet

Angle of depression of near side = 16.5°

Angle of depression of far side = 10.5°

Using trigonometry :

We can obtain x and y as shown in the attached picture :

Tanθ = opposite / Adjacent

Adjacent = height of cliff = 320 Feets

For the near side :

Tanθ = opposite / Adjacent

Tan (16.5°) = x / 320

0.2962134 = x / 320

x = 0.2962134 * 320

x = 94.788318 Feets

For the far side :

Tanθ = opposite / Adjacent

Tan (10.5°) = x / 320

0.1853390 = x / 320

x = 0.1853390 * 320

x = 59.308494 Feets

Length of island = (59.308494 + 94.788318) feet

= 154.10 Feets

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 a
olga2289 [7]

Step-by-step explanation:

For oil container in the shape of a cylinder

radius (r) = 6 m

height (h) = 7 m

TSA of Cylinder

= <em><u>2πr ( r + h) </u></em>

= 2 * 3.14 * 6 ( 6 + 7)

= 2 * 3.14 * 6 (13)

= 2 * 3.14 * 6 * 13

= 489.84 square meter

<em>Now, </em><em> </em>

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.
