The rear wheel of a lawn tractor has a 20-inch radius. find the angle (in radians) through which a wheel rotates in 23 seconds if the tractor is traveling at a speed of 13 miles per hour? round to the nearest tenth if necessary.

263.12 radians

Step-by-step explanation:

The length of the rear wheel is given by:

The distance traveled by the lawn tractor in 23 seconds is:

The angle through which a wheel rotates is given by:

The wheel rotates through a 263.12 radians angle.

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m
