Answer:
15.71
Explanation:
Since this is a
semicircle
, the angle measure of the arc is going to be
180
∘
. And they said that the diameter is
10
, so we can update the formula:
m
360
π
d
180
360
π
(
10
)
0.5
π
10
5
π
Use your calculator to find the value of
5
π
or use the number
3.1415927
for
π
if you have to do it manually.
5
π
=
15.71
So the arc measure of the semi circle is
15.71
