If the arc of a circle of radius 30 cm has a length of 19 cm, then the angle (in degrees, rounded off to two decimal places) subtended at the centre of the circle is:
(Take π = 22/7)
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 36.27
Formula used
Length of an Arc = θ × (π/180) × r
Calculation
Length of an Arc = θ × (π/180) × r
19 = θ × (π/180) × 30
θ = 36.27
