Answer:
How to solve ???
Arc Length = θ × (π/180) × r, where θ is in degree.
Radius and the sector area:-
- Multiply the sector area by 2.
- Then divide the result by the radius squared (the units should be the same) to get the central angle in radians.
- Multiply the central angle by the radius to get the arc length.
Let's solve ur question :-
Answer :-
The Arc length of the given partial circle is 4π units or 12.56 units .
Used formulae :-
- The length of the Arc is "I" units , the radius "I" units and the angle subtended by the Arc at the center is "X" is ( X° / 360° ) x 2πr units .
- Circumference of the circle = 2πr units .
