Find the length of the arc of a circle with radius 5 cm, if its central angle is 70°. |
$\frac{70}{18}$π cm $\frac{35}{18}$π cm $\frac{15}{18}$π cm $\frac{7}{18}$π cm |
$\frac{35}{18}$π cm |
Given circle with radius = 5 cm Circumference = 2Πr = 10Π (For 360º) Length of arc for 70º = 10Π * 70/360 = 70Π/36 The correct answer is Option (2) → $\frac{35}{18}$π cm |
