We know that
area of the circle=pi*r²
if 360° (full circle) has an area of-------------> pi*r²
110°------------------------------> 40 units²
pi*r²=40*360/110--------> pi*r²=130.91------> r²=130.91/pi-----> r²=41.69
r=6.46 units
the answer is
the radius is 6.46 units
Use: (a + b)(c + d) = ac + ad + bc + bd

Answer:
d. x² + 6x +8
Y=3.5x+4
a) 5=3.5x+4, 3.5x=1, x=1/3.5=2/7
b) y=3.5*10+4=35+4=39
Answer: Subtract -5 from 15, or 15- -5= 15+5. The distance would be 20.
