The arc is defined by an angle of 1.05 radians, and a length of 1.05 units.
<h3 /><h3>How to get the angle in radians?</h3>
Remember the relation:
180° = 3.14 radians.
Then:
60° = (60°/180°)*3.14 rad = 1.05 rad.
Now, for a circle of radius R, an arc defined by an angle θ has a length:
L = θ*R
Then the length of this arc is:
L = 1.05*1 unit = 1.05 units.

The answer is B
you can substitute the(x,y)in the equation to find out the answer.
For example,Is (3,0) a point on 1/3x+y=15.
By Substitute x=3 and y=0 to the equation
1/3(3)+(0)=1,which is =/=15.
So you know that (3,0) is not a point on the equation
