By giving just the radius and asking for the arc length of that circle your answer will be without math is 22

But;

Let’s do same math!

Arc length = (()/360)⋅2⋅⋅

In this case angle of arc was not specified so: 360∘

Arc length = ((360)/360)⋅2⋅⋅11

I can’t figure out what the half circle means the answer options are 163,129,149 and 186
vodka [1.7K]

Answer: 129

Step-by-step explanation: First find the area of the circle. Since we know the area of a circle is πr²  (pi multiplied by the radius squared) we can find the area of the half circle. The radius is 5 (because radius is half of the diameter)

Area=3.14(5)²

       =3.14(25)

       =78.5

But since this is just a half circle, divide this by 2

That will get 39.25

Then add this to the area of the rectangle (L*W) which is 90

That will get about 129
