One revolution = 360=2pi
If it complete one revolution in 2 min then the wheel will complete 15 revolution in 30 min
And if we talk about distance then = perimeter of wheel= 2pi r
R=1.5
=2x 1.5x pi
=3pi in one revolution
In 15 revolution = 3pi x 15= 45pi
If it complete one revolution in 2 min then the wheel will complete 15 revolution in 30 min
And if we talk about distance then = perimeter of wheel= 2pi r
R=1.5
=2x 1.5x pi
=3pi in one revolution
In 15 revolution = 3pi x 15= 45pi
