Answer 1

EXPLANATION:

Given;

We are given a sector of a circle with the following dimensions;

$\begin{gathered} radius=12 \\ central\text{ }angle=\frac{\pi}{6} \end{gathered}$

Required;

We are required to calculate the area of the sector with the details given.

Step-by-step solution;

To calculate the area of a sector with the central angle given in radians, we will use the following formula;

$Area\text{ }of\text{ }a\text{ }sector=\frac{\theta}{2\pi}\times\pi r^2$

We can now substitute and solve;

$Area=\frac{\frac{\pi}{6}}{2\pi}\times\pi r^2$$Area=(\frac{\pi}{6}\div\frac{2\pi}{1})\times\pi r^2$$Area=(\frac{\pi}{6}\times\frac{1}{2\pi})\times\pi\times12^2$$Area=\frac{1}{12}\times144\times\pi$$Area=12\pi$

ANSWER:

In terms of pi the area of the sector is

$undefined$
