Find the area of the shaded sector of a circle. Leave ur answer in terms of pi
1 answer:
The area of the shaded sector of a circle is 64 pie cm^2
Here we are given that there is a circle: whose radius is cm and the angle formed by two radius that is angle of the sector is
.
The area of the sector of circle is basically the area of the arc of a circle.
The two combination of two radii forms the sector of a circle while the arc is in between these two radii.
Area of sector is given by:
.л
Substituting the given value in the formula of area of sector:
Area of sector is=
We get after solving,
Area of sector= pie cm^2
So from the given options, option 4 is correct.
Hence the area of the sector is 64 pie cm^2

The orthocenter is the meet of the altitudes. We see AC is parallel to the x axis so the perpendicular is the altitude through B.
Between A and B we have slope (2 - -2)/(-2 - -3) = 4 so perpendicular slope -1/4 through C(2,-2):
For the y coordinate of the orthocenter we substitute in x=-2.
So the orthocenter is (x,y)=(-2,-1)
Answer: (-2,-1)
