Find the arc length of a semi circle with 10 diameter

15.71

Step-by-step 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

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

=

15.71

So the arc measure of the semi circle is

15.71

my answer is$ 12

step-by-step explanation:

because 15 -2=12
