jK is 3.7 inches long

Step-by-step explanation:

Recall that the length of the circumference of a circle of radius "R" is given by the formula:

which corresponds to the "arc length" with a central angle of ,

so we can create the following proportionality:

which can be rounded to the nearest tenth as: 3.7 in

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
