Answer:
Therefore the measure of the central angle is 45.86°.
Step-by-step explanation:
Given:
Radius = 9 cm
arc length = 7.2 cm
pi = 3.14
To Find:
Central angle = θ =?
Solution:
If the θ measured in degree then the arc length is given as
Where r = radius, θ = Central angle
On substituting the values we get
Therefore the measure of the central angle is 45.86°.
