The area of a sector with a central angle of 2π/9 radians and a diameter of 20.6 mm is 37.01 mm²
It is given that
Central angle α= 2π/9
Diameter d= 20.6mm
So, radius r= 10.3mm
What is the formula for the area of the sector?
The area of a sector with central angle α and radius r is 0.5*r²*α
So, area of given sector = 0.5*10.3² * 2π/9
Area of given sector = 37.01 mm²
Therefore, the area of a sector with a central angle of 2π/9 radians and a diameter of 20.6 mm is 37.01 mm².
