The Curved Sides of Large Storage Tanks: Calculating the Approximate Area to be Painted

When it comes to painting large storage tanks at a refinery, the curved sides of these tanks pose a significant challenge. The area to be painted is not a simple rectangle, but rather a complex curved surface. In this article, we will explore how to calculate the approximate area of each tank that will be painted.

To calculate the area of the curved sides of a tank, we need to understand the geometry of the tank. Let's assume that the tank is a cylindrical shape, with a circular base and a curved side that extends from the base to the top of the tank. The curved side of the tank is the area that needs to be painted.

Calculating the Area of a Circular Segment

The curved side of the tank can be thought of as a circular segment, which is a portion of a circle. To calculate the area of a circular segment, we need to know the radius of the circle and the central angle of the segment.

Let's assume that the radius of the tank is $r$ feet, and the central angle of the segment is $\theta$ degrees. The area of the circular segment can be calculated using the following formula:

$$A = \frac{1}{2} r^2 (\theta - \sin \theta)$$

Calculating the Area of the Curved Side of the Tank

To calculate the area of the curved side of the tank, we need to know the radius of the tank and the height of the tank. Let's assume that the radius of the tank is $r$ feet, and the height of the tank is $h$ feet.

The curved side of the tank is a circular segment, and we can use the formula above to calculate its area. However, we need to know the central angle of the segment, which is not given. To calculate the central angle, we can use the following formula:

$$\theta = \frac{360}{2\pi} \arccos \left(1 - \frac{h}{r}\right)$$

Substituting the Values

Now that we have the formulas, let's substitute the values given in the problem. We are given that the radius of the tank is 50 feet, and the height of the tank is 100 feet.

Using the formula above, we can calculate the central angle of the segment:

$$\theta = \frac{360}{2\pi} \arccos \left(1 - \frac{100}{50}\right)$$

$$\theta = \frac{360}{2\pi} \arccos \left(1 - 2\right)$$

$$\theta = \frac{360}{2\pi} \arccos \left(-1\right)$$

$$\theta = \frac{360}{2\pi} \left(-\frac{\pi}{2}\right)$$

$$\theta = 90$$

Now that we have the central angle, we can calculate the area of the circular segment:

$$A = \frac{1}{2} r^2 (\theta - \sin \theta)$$

$$A = \frac{1}{2} (50)^2 (90 - \sin 90)$$

$$A = \frac{1}{2} (2500) (90 - 1)$$

$$A = \frac{1}{2} (2500) (89)$$

$$A = 1,212,500$$

However, this is not the correct answer. We need to calculate the area of the curved side of the tank, which is a portion of the circular segment.

To calculate the area of the curved side of the tank, we need to know the length of the arc of the segment. The length of the arc can be calculated using the following formula:

$$L = \frac{\theta}{360} 2\pi r$$

$$L = \frac{90}{360} 2\pi (50)$$

$$L = \frac{1}{4} 2\pi (50)$$

$$L = \frac{1}{2} \pi (50)$$

$$L = 25\pi$$

Now that we have the length of the arc, we can calculate the area of the curved side of the tank:

$$A = \frac{1}{2} r^2 (\theta - \sin \theta)$$

$$A = \frac{1}{2} (50)^2 (90 - \sin 90)$$

$$A = \frac{1}{2} (2500) (90 - 1)$$

$$A = \frac{1}{2} (2500) (89)$$

$$A = 1,212,500$$

$$A = \frac{1}{2} L h$$

$$A = \frac{1}{2} (25\pi) (100)$$
