The formula for area of sector is
Here = 185°
Now diameter = 6.4m
Radius = 1/2 diameter = 1/2 (6.4) = 3.2m
Substituting the values we get
Area of sector
=
The area of the sector is 16.5m²
Option C) is the right answer
Step-by-step explanation:
m=5/7
m1=m2=5/7
L;y-(-2)=5/7(x-(-5)
y+2=5/7(x+5)
7y+14=5X+25
7y-5x=11 is parallel lines
m1*m2=-1 is perpendicular lines
m2=-1*7/5
m2=-7/5
L;y+2=-7/5(x+5)
5Y+10=-7x-35
5y+7x=-45 is perpendicular lines
