central angle of a circle whose radius is 8 cm and intercepted arc length is 7.2 cm is 0.9 radians
Step-by-step explanation:
We need to find the central angle of a circle whose radius is 8 cm and intercepted arc length is 7.2 cm.
arc length l== 7.2 cm
radius =r= 8 cm
central angle=Ф = ?
The formula used is:

Putting values:

So, central angle of a circle whose radius is 8 cm and intercepted arc length is 7.2 cm is 0.9 radians
