Introduction

In this article, we will delve into the world of geometry and mathematics to explore the possibility of creating 18 circle-shaped tin lids from a rectangular zinc selmbar with a size of 150 × 90 cm. We will use mathematical formulas and calculations to determine the feasibility of this project and provide a step-by-step guide on how to achieve it.

Understanding the Problem

The problem at hand is to create 18 circle-shaped tin lids from a rectangular zinc selmbar with a size of 150 × 90 cm. The diameter of each circle-shaped tin lid is 28 cm. To begin, we need to understand the relationship between the area of the rectangular zinc selmbar and the area of each circle-shaped tin lid.

Calculating the Area of the Rectangular Zinc Selmbar

The area of a rectangle is given by the formula:

Area = Length × Width

In this case, the length of the rectangular zinc selmbar is 150 cm and the width is 90 cm. Therefore, the area of the rectangular zinc selmbar is:

Area = 150 × 90 = 13500 cm²

Calculating the Area of Each Circle-Shaped Tin Lid

The area of a circle is given by the formula:

Area = π × Radius²

Since the diameter of each circle-shaped tin lid is 28 cm, the radius is half of the diameter, which is:

Radius = 28 / 2 = 14 cm

Now, we can calculate the area of each circle-shaped tin lid:

Area = π × 14² = 3.14 × 196 = 615.44 cm²

Determining the Number of Circle-Shaped Tin Lids

To determine the number of circle-shaped tin lids that can be created from the rectangular zinc selmbar, we need to divide the area of the rectangular zinc selmbar by the area of each circle-shaped tin lid:

Number of Circle-Shaped Tin Lids = Area of Rectangular Zinc Selmbar ÷ Area of Each Circle-Shaped Tin Lid = 13500 ÷ 615.44 = 22.0

However, we are given that 18 circle-shaped tin lids can be created from the rectangular zinc selmbar. This suggests that the area of the rectangular zinc selmbar is sufficient to create 18 circle-shaped tin lids.

Calculating the Remaining Area

To confirm this, we can calculate the remaining area of the rectangular zinc selmbar after creating 18 circle-shaped tin lids:

Remaining Area = Area of Rectangular Zinc Selmbar - (Area of Each Circle-Shaped Tin Lid × Number of Circle-Shaped Tin Lids) = 13500 - (615.44 × 18) = 13500 - 11065.92 = 2434.08 cm²

Since the remaining area is greater than zero, it is possible to create 18 circle-shaped tin lids from the rectangular zinc selmbar.

Conclusion

In this article, we explored the possibility of creating 18 circle-shaped tin lids from a rectangular zinc selmbar with a size of 150 × 90 cm. We used mathematical formulas and calculations to determine the feasibility of this project and provided a step-by-step guide on how to achieve it. The results showed that the area of the rectangular zinc selmbar is sufficient to create 18 circle-shaped tin lids, with a remaining area of 2434.08 cm².

Step-by-Step Guide

To create 18 circle-shaped tin lids from a rectangular zinc selmbar with a size of 150 × 90 cm, follow these steps:

Calculate the area of the rectangular zinc selmbar using the formula: Area = Length × Width.
Calculate the area of each circle-shaped tin lid using the formula: Area = π × Radius².
Determine the number of circle-shaped tin lids that can be created from the rectangular zinc selmbar by dividing the area of the rectangular zinc selmbar by the area of each circle-shaped tin lid.
Calculate the remaining area of the rectangular zinc selmbar after creating the desired number of circle-shaped tin lids.
If the remaining area is greater than zero, it is possible to create the desired number of circle-shaped tin lids from the rectangular zinc selmbar.

Limitations

This article assumes that the rectangular zinc selmbar is a perfect rectangle with no defects or irregularities. In reality, the selmbar may have imperfections that affect the area available for creating circle-shaped tin lids. Additionally, the calculations assume that the circle-shaped tin lids are perfect circles with no defects or irregularities.

Future Work

Future work could involve exploring the possibility of creating circle-shaped tin lids from other shapes, such as triangles or squares. Additionally, the calculations could be refined to account for imperfections in the rectangular zinc selmbar and the circle-shaped tin lids.
