Asmaller than average beach ball has a volume of 36 pi in ^3, what is its radius

3 inches

Step-by-step explanation:

The volume of  a sphere = (4/3) π r^3 , therefore:-

36 π = (4/3)  π r^3

r^3 = 36 π /  (4/3)  π

r^3 = 36 *3 / 4

r^3 = 27

Therefore r = 3 ins   (answer).

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.
