The curved part of this figures is a semicircle.
what is the best approximation for the area of this figure?

28+16.25π units²

28+8.125π units²

14+16.25π units²

14+8.125π units²

14+8.125π units²

Step-by-step explanation:

By the given diagram,

The diameter of the semicircle = The line segment having the end points (-4,-2) and (3,2),

 unit,

Thus, the radius of the semicircle = √65/2 unit,

⇒    

square unit.

Now, by the given diagram,

The area of the triangle having the vertices (-4,-2), (3,2) and (-4,2)  ( By the coordinate form of area of a triangle formula )

square unit,

Hence, the total area of the given figure = Area of semicircle having diameter √65 + area of triangle having vertices (-4,-2), (3,2) and (-4,2)

square unit.

⇒ Fourth option is correct.

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s
