Introduction

In this problem, we are given a rectangular park where a cow is tied to a pole on one end with a string of 14 meters. The cow can graze in a circular area around the pole, and we need to find the area over the area of the cow can graze. This problem involves geometry and trigonometry, and we will use these concepts to solve it.

Understanding the Problem

Let's visualize the problem. We have a rectangular park with a pole on one end, and a cow tied to the pole with a string of 14 meters. The cow can graze in a circular area around the pole, and we need to find the area over the area of the cow can graze.

Key Concepts

To solve this problem, we need to understand the following key concepts:

Geometry: We need to use geometric concepts such as points, lines, and shapes to understand the problem.
Trigonometry: We need to use trigonometric concepts such as angles, triangles, and circles to solve the problem.
Area: We need to find the area of the circular region where the cow can graze.

Finding the Area of the Circular Region

To find the area of the circular region where the cow can graze, we need to use the formula for the area of a circle:

A = πr^2

where A is the area of the circle, and r is the radius of the circle.

In this case, the radius of the circle is the length of the string, which is 14 meters. So, we can plug in the value of the radius into the formula:

A = π(14)^2

A = 3.14 × 196

A = 615.76

So, the area of the circular region where the cow can graze is approximately 615.76 square meters.

Finding the Area of the Rectangular Park

To find the area of the rectangular park, we need to use the formula for the area of a rectangle:

A = length × width

We are given that the length of the rectangular park is 28 meters, and the width is 14 meters. So, we can plug in the values of the length and width into the formula:

A = 28 × 14

A = 392

So, the area of the rectangular park is 392 square meters.

Finding the Area Over the Area of the Cow Can Graze

To find the area over the area of the cow can graze, we need to subtract the area of the circular region from the area of the rectangular park:

Area over the area of the cow can graze = Area of the rectangular park - Area of the circular region

Area over the area of the cow can graze = 392 - 615.76

Area over the area of the cow can graze = -223.76

However, we cannot have a negative area, so we need to take the absolute value of the result:

Area over the area of the cow can graze = |-223.76|

Area over the area of the cow can graze = 223.76

So, the area over the area of the cow can graze is approximately 223.76 square meters.

Conclusion

In this problem, we used geometric and trigonometric concepts to find the area over the area of the cow can graze. We first found the area of the circular region where the cow can graze, and then we found the area of the rectangular park. Finally, we subtracted the area of the circular region from the area of the rectangular park to find the area over the area of the cow can graze.

Final Answer

The final answer is: 223.76

Discussion
