Answer:
69.81 sq. m. (rounded to 2 decimal places)
Step-by-step explanation:
The sector of a circle is "part" or "portion" of a circle. The formula for the area of a sector is:
Where
is the central angle
r is the radius
Given the figure, the arc is given as 80 degrees, but not the central angle of the shaded sector. But from geometry we know that the central angle and the intercepted arc have the same measure. So we can say:
Also, the radius of the circle shown is 10 meters, so
r = 10
Now, we substitute in formula and find our answer:
Thus,
The area of the shaded sector is 69.81 sq. meters.

Answer:
Step-by-step explanation:
<em>The measure of an interior angle of a regular polygon is given. Find the number of sides in the polygon.</em>
To find the number of sides of a polygon when given the sum of interior angles, we use the formula: Sum of interior angles = (n - 2) × 180, where n is the number of sides.
