Answer:

162.4283 in^2 (hope this is correct!)

Step-by-step explanation:

Area using side length only.

n = 8

Area = n (s/2)^2 / tan( π /n)

= 8(5.8/2)^2 / tan ( π /8)

= 162.4283 in^2

Given:

Radius of the circle = 4 meters

Measure of arc = 135 degrees

To find:

The area of the sector bounded by the given arc.

Solution:

Formula for area of a sector is:

$A=\pi r^2\times \dfrac{\theta}{360^\circ}$

Where, r is the radius and $\theta$ is the central angle or measure of intercepted arc.

Putting $r=4,\ \theta =135^\circ$ in the above formula, we get

$A=\pi \times (4)^2\times \dfrac{135^\circ}{360^\circ}$

$A=\pi \times 16\times \dfrac{3}{8}$

$A=\pi \times 2\times 3$

$A=6\pi$

Therefore, the exact area of the given sector is $6\pi$ square meters.
