Step-by-step explanation:
length of arc, l = radius x theta(in radians)
theta ( radians) = 72 x pi/ 180 = 1.2566
l = 10 x 1.2566 = 12.566 cm

Answer:
Step-by-step explanation:
The central angle=72°
Radius of the arc=10 cm
So length of the arc=∅/360×(2πr)
=(72/360)×(2×3.14×10)
=1/5×2×3.14×10
=3.14×4=12.56cm
Hope you got it.
