A wheel makes 360 revolutions in one minute. Through how many radians

1.	A wheel makes 360 revolutions in one minute. Through how many radians doesit turn in one second?Find the degree measure of the angle subtended at the centre of a circle ofradius 100 cm by an are of length 22 cm (Use
Answer» in 1 revolution - 2π radian is the angle that is covered. so in 360 revolution 2π×360 = 720π radians. now in 1 sec radians will be 720π/60 = 12π

Answer»

in 1 revolution - 2π radian is the angle that is covered.

so in 360 revolution 2π×360 = 720π radians.

now in 1 sec radians will be 720π/60 = 12π
