Question on: JAMB Mathematics - 2001
The chord ST of a circle is equal to the radius, r, of the circle. Find the length of arc ST.
A
πr/6
B
πr/2
C
πr/12
D
πr/3
Ask EduPadi AI for a detailed answer
Correct Option: D
Since ST = the radius r, => SOT is equilateral.
Each angle = 60°
Length of arc ST = θ/360 x 2πr
= 60/360 x 2 x π x r = πr/3
