Ex 3.1, 3 A wheel makes 360 revolutions in one minute. Through how many radians does it turn in one second? Number of revolutions in 1 minute = 360 Number of revolutions in 60 second = 360 So, Number of revolutions in 1 second = 360/60 = 6 Now, finding angle made in 6 revolutions Angle made in 1 revolution = 360° Angle made in 6 revolution = 6 × 360° = 6 × 360 × 𝝅/𝟏𝟖𝟎 = 6 × 2 × 𝜋 = 12 𝝅 radians
