The circumference of a circle can be found using the formula C = 2r. Which is an equivalent equation solved for r? r = C r = C(2) r = r equals StartFraction C Over 2 pi EndFraction. r = r equals StartFraction 2 pi Over C EndFraction.

c is the correct answer

step-by-step explanation:

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.
