Question

2. A wheel makes 360 revolutions in one minute.
Through how many radians does it turn in one
second ?​

Answer 1

1minute=60 s

The wheel,

In 60s rotates 360°

In 1s rotates (360÷60)°

=60°

=(60π÷180)c

=3|π c

Answer 2

${ \huge{\boxed{\tt {\color{red}{Answer}}}}}$

Number of revolutions made by the wheel in 1 minute = 360

1 minute = 60 seconds

Number of revolutions in 1 second = 360/60 = 6

Angle made in 1 revolution = 360°

Angles made in 6 revolutions = 6 × 360°

Radian measure of the angle in 6 revolutions = 6 × 360 × π/180

= 6 × 2 × π

= 12π

Hence, the wheel turns 12π radians in one second
