Question

A central angle of a circle whose radius is 25 centimeters subtends an arc whose length is 5π/12 centimeters.

What is the radian measure of the central angle?

Answer 1

Answer: The answer is pi/60

Step-by-step explanation: I took the test.

Answer 2

central angle/full circle = arc length/circumference

Θ/2π = (5π/12 cm)/(2π * 25 cm)

Θ = 2π(5π/12 cm)/(2π * 25 cm)

= (2π)(5π cm)/(12)(2π)(25 cm)

= π/60
