What is the approximate area of the shaded region? Circumscribed square with side length 8 meters. The four regions between the
circle and square are shaded. 178.5 square meters 64 square meters 13.76 square meters 21.5 square centimeters
1 answer:
Answer:
13.76 square meters
Step-by-step explanation:
The side of square is 8 meters.
So, the diameter of circle = 8 meters.
⇒ Radius = (diameter of circle) ÷ 2 = 8 ÷ 2 = 4 meters
Shaded region = Area of square - Area of circle
= (Side × Side) - π × (radius)²
= 8 × 8 - π × 4 × 4 {∵ π = 3.14 or 22÷7}
= 64 - 50.24
= 13.76 square meter

Step-by-step explanation:
From the diagram, we can see that:
Then by Alternate Interior Angles:
From vertical angles, we also know that:
This is all we can gather from the given image. Knowing only three pairs of angles cannot prove congruence, as proving congruence requires at least one side.
Congruence cannot be determined.
If you divide both sides by -4 you get
So, you wrote the equation in the form y=kx, and in this form k is the constant of variation. So, the constant is -2.
