Concept:
Angle formed by an arc at the centre
= length of the arc / radius
Given:
Length of the arc = 2.5 cm
Radius of the circle = 15 cm
Angle formed by the arc
= 2.5 / 15
= 25 / 150
= 1/6 radians
= 1/6 × 180 / pi degrees
= 30 ×7 /22 degrees
= 210 /22 degrees
= 9 degrees 32 minutes 43 seconds
I hope this answer helps you
