As x approaches 2 from the left, y approaches 2+3 (or 5) from below. But because of the open parenthesis at the right of (-infinity, 2), as well as the jump in y value (from 5 to 1) at x =2, the limit does not exist.
We use direct proportionality:
360⁰......Pi×R² (full circle)
120⁰.......x
x=120×pi×R²/360=pi×R²/3
x=pi×4²/3=16.76mi²
A=3×pi cm², for an angle of 2×pi/3=120⁰
In a similar way we compute the area of the full circle:
360.........x
120..........3×pi
x=3×pi×360/120=9×pi=3²×pi.
Thus the radius is 3cm.
The first answer is right.
Analyze the picture. Notice the 'rigjt angle symbols'. Those mean lines are perpendicular. You can also use them to determine if two lines are parallel.
