Question

The circumference of oC is 56 cm. What is the length of AB (the minor arc)?

Answer 1

Length of arc AB is 14. So, option E is correct

Explanation:

Answer 2

Length of arc AB is 14. So, option E is correct

Explanation:

Circumference of circle == 56 cm

We need to find length of arc AB?

Formula used will be l = rФ

We know, C = 2πr

56 = 2πr

56/2π = r

=> r = 8.91

Ф = 90° = 1.57 radians

So, l= rФ

l = 8.91 * 1.57

l = 13.98 = 14

So, Option E is correct
