Question

the length of an arc is 10cm find angle subtended by arc if the circumference of the circle of which the arc form part 60cm​

Answer 1

9514 1404 393

Answer:

60° = π/3 radians

Explanation:

The 10 cm length of the arc is 1/6 of the 60 cm length of the circumference of the circle. That means the angle measure of the arc is 1/6 of the total angle measure of a circle.

arc = 360°/6 = 60°

arc = (2π radians)/6 = π/3 radians
