Question

The radius of the circle is 3.5 and the area of the sector is 3.85 sq cm Find the measure of the arc of the circle ​

Answer 1

Answer:

area of sector =2πr@/360 (assume

this@as theta)

3.85=(2×22/7×3.5@)/360

3.85=(44×0.5@)/360

3.85=22@/360

3.85×360=22@

(3.85×360)/22=@

1386/22=@

63=@

length of arc=2πr@/360

=(2×22/7×3.5)63/360

=(44×0.5) 7/40

= (22×7)/40

=(11×7) /20

= 77/20

=3.75
