A roundabout in Eldoret city has a circular flower bed with a radius of 12 m. A section of the edge is decorated with colourful flowers, forming an arc length of 12.57 m.
Given:
Radius (r) = 12 m
Arc Length = 12.57 m
π = 3.142
Formula:
Arc Length = (θ/360°) × 2πr
Therefore: θ = (Arc × 360°)/(2πr)
Calculate the angle it subtends at the centre of the circular flower bed.
