Tamar Is Building A Fence Around A Circular Lot That Has A Radius Of 26 Meters.Each Linear Meter Of Fencing Cost $8. How Much Will The Circular Fence Cost Tamar?Round To The Nearest Dollar.

Introduction

In this article, we will explore the concept of calculating the cost of a circular fence. We will use the formula for the circumference of a circle to determine the total length of fencing required and then multiply it by the cost per meter to find the total cost.

Understanding the Problem

Tamar is building a fence around a circular lot that has a radius of 26 meters. Each linear meter of fencing costs $8. To find the total cost of the fence, we need to calculate the circumference of the circle and then multiply it by the cost per meter.

The Formula for the Circumference of a Circle

The formula for the circumference of a circle is:

C = 2πr

Where C is the circumference, π is a mathematical constant approximately equal to 3.14, and r is the radius of the circle.

Calculating the Circumference

Using the formula for the circumference of a circle, we can calculate the circumference of the circular lot as follows:

C = 2πr C = 2 × 3.14 × 26 C = 163.08 meters

Calculating the Total Cost

Now that we have the circumference of the circle, we can calculate the total cost of the fence by multiplying the circumference by the cost per meter:

Total Cost = Circumference × Cost per Meter Total Cost = 163.08 × 8 Total Cost = 1304.64 dollars

Rounding to the Nearest Dollar

Since we are asked to round the total cost to the nearest dollar, we can round 1304.64 to 1305 dollars.

Conclusion

In this article, we used the formula for the circumference of a circle to calculate the total length of fencing required for a circular lot with a radius of 26 meters. We then multiplied the circumference by the cost per meter to find the total cost of the fence. The total cost of the fence is 1305 dollars.
