Question

A wheel maker 120 revolutions in 1 minute. Then the angle
in radian covered by the wheel in 2 seconds is
​

Answer 1

Step-by-step explanation:

Answer:-

= \frac{30}{(60 \times 2)}=

(60×2)

30

= 0.25 revolution

revelation 1 = 2 π rad

0.25 revolution = π / 2 rad

Answer 2

Answer:

The angle in radian covered by a wheel in 2 seconds is 8π.

Step-by-step explanation:

Number of revolutions in 1 minute = 120

Number of revolutions in 60seconds = 120

so, number of revolutions in 1 second = $\frac{120}{60} =\frac{12}{6} =2$

Number of revolutions  in 2 seconds = 2 × $\frac{120}{60}$ = 4

Angle made in 1 revolution  = 360°

Angle made in 4 revolution = 4×360°

Radian measure = $\frac{\pi }{180}$ × degree measure.

Radians made in 4 revolution = 4× 360× $\frac{\pi }{180}$ = 4×2×π = 8π

Therefore, the angle in radian covered by a wheel in 2 seconds is 8π.
