Sagot :
a circle divided into five equal parts:
1 part = 1/5
a.) A circle has a full 360 degrees.
1/5 (360 degrees) = 72 degrees
Each arc has a measure of 72 degrees.
The central angle = degree measure of intercepted arc
b.) Step 1: Find the circumference (C), when radius = 3 cm; π=3.14 (pi)
C = 2π r
C = 2 (3.14) (3 cm)
= (6.28) (3 cm)
= 18.84 cm
Step 2: Find the length (in cm) of each arc.
Arc length = central angle × Circumference
360 dgrees
Arc length = 72 degrees x 18.84 cm
360 degrees
Arc length = (1/5) ( 18.84 cm)
Arc length = 3.768 cm or 3. 77 cm rounded off to the nearest hundredths
Each arc has a length of 3.77 cm.
c.) Pentagon, a polygon with five sides, is formed.

a. each arc measures 72
b. 3.78 cm is the length of each arc
c. a regular polygon having 5 equal sides called PENTAGON. :)
