Answer:
Arc length (AB ) = 9 cm .
Step-by-step explanation:
Given : The circumference of C is 72 cm and The center angle is 45.
To find : What is the length of arc AB (the minor arc).
Solution : We have given that
circumference of C = 72 cm.
The center angle = 45.
Formula of arc length = [tex]2\ pi\ r (\frac{central\ angle}{360})[/tex].
We have circumference = 2 pi r
Substitute the values arc length = [tex]72 (\frac{45}{360})[/tex].
Arc length = [tex](\frac{3240}{360})[/tex].
= 9 cm
Therefore ,Arc length (AB ) = 9 cm .
