Answer:

The length of the arc is 4π

Step-by-step explanation:

To calculate the arc we first have to calculate the perimeter of the circle

r = 10

C = π * 2r

We replace the value of r

C = π * 2 * 10

C = 20π

Now that we know the perimeter we have to multiply it by 72/360 which is the portion marked with respect to the complete circle

20π * 72/360 = 4π
