What is the Area of the Sector of a Circle with $\theta=75^{\circ}$ and a Radius of 4 Feet?

In geometry, a sector of a circle is a region bounded by two radii and an arc. The area of a sector can be calculated using the formula: $A = \frac{\theta}{360} \pi r^2$, where $\theta$ is the central angle in degrees, $\pi$ is a mathematical constant approximately equal to 3.14159, and $r$ is the radius of the circle. In this article, we will calculate the area of a sector of a circle with a central angle of $75^{\circ}$ and a radius of 4 feet.

Understanding the Formula

The formula for the area of a sector is: $A = \frac{\theta}{360} \pi r^2$. This formula can be broken down into three main components:

• $\theta$: The central angle in degrees. In this case, the central angle is $75^{\circ}$.
• $\pi$: A mathematical constant approximately equal to 3.14159.
• $r^2$: The square of the radius of the circle. In this case, the radius is 4 feet.

Calculating the Area

To calculate the area of the sector, we can plug in the values of $\theta$, $\pi$, and $r^2$ into the formula:

$A = \frac{75}{360} \pi (4^2)$

First, we need to calculate the value of $4^2$, which is equal to 16.

$A = \frac{75}{360} \pi (16)$

Next, we can calculate the value of $\frac{75}{360}$, which is equal to $\frac{5}{24}$.

$A = \frac{5}{24} \pi (16)$

Now, we can multiply $\frac{5}{24}$ by 16 to get $\frac{80}{24}$.

$A = \frac{80}{24} \pi$

Finally, we can multiply $\frac{80}{24}$ by $\pi$ to get the final answer.

Final Calculation

To calculate the final answer, we can multiply $\frac{80}{24}$ by $\pi$:

$A = \frac{80}{24} \pi$

$A = \frac{20}{6} \pi$

$A = \frac{10}{3} \pi$

$A = 10.472 \pi$

Since $\pi$ is approximately equal to 3.14159, we can multiply $10.472$ by $\pi$ to get the final answer:

$A = 10.472 \times 3.14159$

$A = 32.969 \, \text{ft}^2$

However, this is not one of the answer choices. Let's try to simplify the calculation.
