There are 2pi radians in a circle

so the fraciton is Θ/(2pi)

so
pir^2 times Θ/(2pi)=pir^2Θ/2pi=Θr^2/2
multiply it by Θ/(2pi)

Answer:

\bf\textbf{Area of the sector = }\frac{\theta}{360}\times \pi\times radius^2

Step-by-step explanation:

\text{The area of the circle is }\pi\times radius^2

Now, To find the area of the sector of the circle we must be given the value of the central angle.

In this case, The central angle of the circle is given to be Θ

Now, The measure of one complete angle is 360

So, to find the area of the sector we need to divide the central angle Θ by 360

Hence, the resultant area of the sector of the circle is given by the formula :

\bf\textbf{Area of the sector = }\frac{\theta}{360}\times \pi\times radius^2

2(2x + 3) = -6(x + 9)
sergeinik [125]

Answer:

Your answer is -6.

Step-by-step explanation:

Simplify 2(2x+3) to get 4x+6  

Then simplify -6(x+9) to get -6x-54

Now you have 4x+6=-6x-54

Move all of the coefficients to one side:

10x+6=-54

Move all of the constants to the other side:

10x=-60

Divide each side by 10:

10/10x=-60/10

To get your answer of -6.

Five friends equally shared half of one large pizza and 1/4 of another large pizza. what fraction of each pizza did each friend
attashe74 [19]
1/2 divide by 5= 1/10
1/4 divide by 5=  1/20                              so    1/10 is also 2/20+1/20=3/20

so the answer is 3/20 of a pizza
