The length of radius of the given circle, r = 5 cm.

The arc makes a 30° angle at the center.

Change degrees to radians for the given angle.

This gives, (30°/360°) * 2π = 0.52 radians which means angle, θ = 0.52 radians

The length of radius of the given circle, r = 10 cm.

The arc makes a 60°angle at the center.

Change degrees to radians for the given angle.

This gives, (60°/360°) * 2π = 1.05 radians, which means angle, θ = 1.05 radians
