A circle has a radius of 10 inches. Find the approximate length of the arc intersected by a central angle of 2π/3

Aleksandr-060686 [28]

Answer: Option 'C' is correct.

Step-by-step explanation:

Since we have given that

Radius of circle = 10 inches

Central angle is given by

$\frac{2\pi }{3}$

As we know the formula for " Length of an arc " :

Length of arc is given by

$l=r\theta\\\\l=10\times \frac{2\pi}{3}\\\\l=10\times \frac{2}{3}\times \frac{22}{7}\\\\l=20.95\ inches$

Hence, length of an arc is 20.95 inches.

Hence, Option 'C' is correct.
