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:
The given points are

The setting would have a interval or 2 units above and below the minimum and maximum of each coordinate.
The given maxium horizontal coordinate is 0.
The given minimum horizontal coordinate is -13.
The given maximum vertical coordinate is 3.
The given minimum vertical coordinate is -7.
Now, we extend each maximum and minimum value by 2 units to create the setting.
So, the setting is

With a scale of 2 units.
The product of the given expression is -120. Option A is correct
<h3>Product of negative numbers.</h3>
Given the expression below as shown;
−5⋅(−3)⋅(−8)
Since the product of two negative number is equal to positive, then;
−5⋅(−3)⋅(−8) = -8(5*3)
Simplify the result to have:
-8 * 15
find the final product
-8 * 15 = -8(5+10)
-8 * 15 = -40 - 80
-8 * 15 = -120
Hence the product of the given expression is -120
