Question

The diameter of a circle is 10cm
find the length of the arc of its
corresponding central angle is 144° (π=3.14)
​

Answer 1

Answer:

12.56

Step-by-step explanation:

Radius of the circle =

2

Diameter

=5cm

Length of an arc subtending an angle θ=

360

θ

×2πR where R is the radius of the circle.

So, length of the arc =

360

144

×2×3.14×5=12.56cm

Answer 2

Radius of the circle = Diameter/2

=5cm

Length of an arc subtending an angle θ

= (θ/360) ×2πR

,where R is the radius of the circle.

So, length of the arc =(144/360)×2×3.14×5

=12.56cm
