The distance a wheel travels is = to the circumference, so C=60inches. Since C=2∏r, r=C/(2∏)
r=60/(2∏)
r=30/∏ inches, or ~9.54929659 inches

When the radius of the wheel is larger than the radius of the axle - which is almost always true.When the radius of the wheel is larger than the radius of the axle - which is almost always true.When the radius of the wheel is larger than the radius of the axle - which is almost always true.When the radius of the wheel is larger than the radius of the axle - which is almost always true.
The mechanical advantage of a wheel and axle is the ratio of the radius of the wheel to the radius of the axle.
If it doesn't slip, it travels one circumference of the rim with each rotation.The circumference = (2 pi) times (the radius) = (2 pi) x (14.75) = 92.677 inches. (rounded)
1 mile = 5280 feet The wheel turns 330 times in 1 mile ie 330 times for 5280 feet So each turn of the wheel = 5280/330 = 176 feet. So, if r is the radius of the wheel, its circumference is 2*pi*r and 2*pi*r = 16 feet so pi*r = 8 feet and r = 8/pi feet = 2.55 feet.
A wheel with a radius of 0.5m has a circumference of 2πr metres. In this example, 2πr = 2π x 0.5 = π metres. The wheel makes 100/π turns when travelling 100 metres, that is 31.831 turns.

He is 75 feet high.
The IMA of a wheel and axle is the radius of wheel divided by the radius of the axle.

Axle.
Radius of wheel: 27.6/2 = 13.8cm
get the circumference of the circle using 2*pi*r (1.2*pi) times that by 40 to get the answer (48*pi)
The mechanical advantage of a wheel and axle is the ratio of the radius of the wheel to the radius of the axle.
If it doesn't slip, it travels one circumference of the rim with each rotation.The circumference = (2 pi) times (the radius) = (2 pi) x (14.75) = 92.677 inches. (rounded)
Radius of the wheel: 24/2 = 12 inches
The mechanical advantage of a wheel and axle is the ratio of the radius of the wheel to the radius of the axle. Ex:- Suppose the radius of the wheel is four times greater than the radius of the axle, every time you turn the wheel once, your force will be multiplied four times.
