An angle has a measure of 61 degrees plus 1.1 radians. Determine the percentage of a circle's circumference cut off by this angle.  %   
Determine the measure of this angle in radians.  radians  
  Determine the measure of this angle in degrees.  degrees 
  Determine the value of s, the arc length (measured in inches) cut off by this angle when centered in a circle with a radius of 2.8 inches.  inches
I need help this is for a test.​

The length of what is left would be 1 1/2 feet long.

First locate the turning point (vertex) of the graph. which is at the coordinates x=5 and y=9 or (5; 9).to determine whether it's a maximum or mininum value, you have to discern whether the vertex's y-value is the highest value or lowest value the graph can reach. since the vertex's y-value, 9 is the highest value the graph can reach, it will be a maximum.another basic way to determine whether the vertex's value is max or min is to see if the graph is smiling or sad. if it's smiling, the turning point/vertex would be a minimum, while a sad parabola would have a maximum y-value at the vertex.
