Answer 2

Step-by-step explanation:

Given:-

In a circle of radius 6 cm and central angle 60°

To find:-

Find the length of arc ?

Solution:-

Given that

Radius of the circle = 6 cm

Angle subtended by the arc at the centre = 60°

We have

r = 6cm

X°=60°

We know that

Length of the arc = (X°/360°)×2πr units

On Substituting these values in the above formula

=> l = (60°/360°)×2×(22/7)×6 cm

=> l = (1/6)×2×22×6/7 cm

=> l = 2×22/7 cm

=> l= 44/7 cm

=> l = 6.2857...cm

Length of the arc = 6.29 cm (approximately)

Answer:-

Length of the arc in the given circle is 2π cm or 6.29 cm

Used formula:-

• Length of the arc = (X°/360°)×2πr units

• X°=Angle subtended by the arc at the centre

• r= radius

• π=22/7
