Calculate the area using the central angle and the arc length.
Code:
x=(a/(y/360))/2;
x^2*(y/360)
x=(a/(y/360))/2;
x^2*(y/360)
| Answer: | (π) cm² |
Example: Find the area of a sector with an arc length of 3 and an angle of 60°.
Find the radius.
3/(60/360)/2 = 9
9 cm;
Find the area.
9²(60/360) = 13.5
Therefore,
A. 13.5 cm²
Find the radius.
