The area of the sector is 0.628(r^2).
According to the statement
we have to find that the area of AOB sector.
So,For this purpose, we know that the
The area of sector of a circle is the amount of space enclosed within the boundary of the sector.
And the formula to calculate is :
Area = Theta/360 *(r^2)Then
from the information is :
angle AOB=72⁰
then substitute in the values then
Area = 72/360 *(pi)(r^2)
Area = 72/360 *(3.14)(r^2)
Area = 0.628(r^2)
The value of the area of the sector of the circle with the help of the formula is 0.628(r^2).
So, The area of the sector is 0.628(r^2).
