A. the area of the sector is 360 - x/ 360 times the area of the whole circle.

b. the area of the sector is equal to . pi r^2/ x

c. the area of the sector is x/360 times the area of the whole circle.

d. the area of the sector is equal to. pi r^2/ 360 - x

C

Step-by-step explanation:

The area of the sector and the whole circle are proportional to the central angles.

a / A = x / 360°

a = (x / 360°) A

So the answer is C.

24

step-by-step explanation:

i assuming that 2 sides are 6 the other 2 sides are 4 cm so 6 times 4 is 24 : )

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
