If the radius of a half-circle is 11... What's the arc length?
pi-3.14

PLEASE I NEED HELP ASAP

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

But;

Let’s do same math!

Arc length = (()/360)⋅2⋅⋅
(
(
a
n
g
l
e
o
f
a
r
c
)
/
360
)
⋅
2
⋅
π
⋅
r

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

Arc length = ((360)/360)⋅2⋅⋅11
(
(
360
)
/
360
)
⋅
2
⋅
π

11

Arc length = 22
π
feet

Answer is a not really sure tho
