Question

a circle has a radius of 4 and an arc in this circle has an central angle of 288 what is the length of the arc​

Answer 1

Answer:

8 cm

Step-by-step explanation:

this is because arc has two radius

first radius + second radius = 8 cm

Answer 2

Given:

• Radius of circle $(R) = 4cm$

• Central angle $(\theta) = 288^\circ$

To Find:

• Length of an arc$(l)$

Solution:

We know that,

Length of an arc is given by ,

               $l=\frac{\pi R \theta}{180}$

Putting the all values given above,

               $l=\frac{\pi \times 4\times 288}{180}$

              $l= 6.4\pi cm$

So, the length of the arc is $6.4\pi cm$
