Well, since we know that in π radians there are 180°, then how many radians in 150°?
<span>-8(5r+6)+9(6r+3)
= -40r - 48 + 54r + 27
= 14r - 21</span>

Step-by-step explanation:
You need to know the formula for the area of a circle , do you?
it's pi*
plug in 1/2 of the diameter , they tell us it's 48 + 6 = 54
54/2 = 27
so
pi*
=2290.2 sq inches
Z-m=z+bx
z-m-z=z+bx-z
-m=bx
bx=-m
bx/b=-m/b; b=0
x=-m/b; b=0
