The area of the sector will be 9π <span>m².
We know, area of circle is given as </span>πr², where r is the radius of the circle.
Here Area of circle,C = <span>72π m²
</span>
Area of a sector that subtends an angle 45°<span> at the center (the area shaded in yellow color) is given as:
A = 72</span>
×
⇒ A = 45×
π m².
⇒ A = 9π m².

<h3>What are linear equations?</h3>Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient
<h3>How to determine the graph of the points on the coordinate plane.?</h3>A system of linear equations is a collection of at least two linear equations.
In this case, the points are given as
(7, 3) and (1, 5)
The point (7, 3) means that:
x = 7 and y = 3
i.e. the point is located 7 units to the right of the origin and 3 units up the origin
Similarly,
The point (1, 5) means that:
x = 1 and y = 5
i.e. the point is located 1 unit to the right of the origin and % units up the origin
Next, we plot the points on the coordinate plane.
