Answer:
or
Step-by-step explanation:
step 1
Find the area of complete circle
The area of the circle is equal to
we have
substitute
step 2
Find the area of the sector
Remember that the area of the complete circle subtends a central angle of 360 degrees
so
using proportion
Find out the area of the region by a central angle of 300 degrees
simplify
----> exact value
Find the approximate value
