8/9k + 9/5 = -4 - 9/7k
Mamont248 [21]

Answer:

k=-1827/685

Step-by-step explanation:

8/9k+9/5=-4-9/7k

8/9k-(-9/7k)=-4-9/5

8/9k+9/7k=-20/5-9/5

56/63k+81/63k=-29/5

137/63k=-29/5

k=(-29/5)/(137/63)

k=(-29/5)(63/137)

k=-1827/685

Find the area of the shaded sector of a circle. Leave ur answer in terms of pi
laila [671]

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 16cm and the angle formed by two radius that is angle of the sector is 90.

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:

Area of sector=\frac{mXY}{360^{0} }.лr^{2}

Substituting the given value in the formula of area of sector:

Area of sector is=\frac{90}{360}\times pie\times r^{2}

We get after solving,

Area of sector= 64 pie cm^2

So from the given options, option 4 is correct.

Hence the area of the sector is 64 pie cm^2
