If you have not already, convert the angle into a radius. xπ/180 where x is the angle in degrees. 

The formula for area is A=r²Ф/2 where r is radius and Ф is angle in radians. 

Solve to find the area. 

Hope I helped :)

What is the slope of this line?
nataly862011 [7]

Answer: -\frac{8}{5}

Remember: RISE/RUN (y/x). Lines that are increasing have a positive slope, and lines that are decreasing have a negative slope.

You can find the slope in two ways:

1. Useful if the line is graphed: count the units between 2 points on the line.

  • Let's use the points (-1, 4) and (4, -4).
  • (-1, 4) is 8 units higher than (4, -4) and 5 units to the left of (4, -4).
  • Because the line is decreasing, the slope is negative.
  • Therefore, the slope is -\frac{8}{5}.

2. Useful if the line is not graphed: find the difference between the y-coordinate values divided by the difference of the x-coordinate values.

  • Let's use the points (-1, 4) and (4, -4).
  • \frac{-4 - 4}{4 - (-1)} = \frac{-8}{5}
  • Therefore, the slope is -\frac{8}{5}.
