Answer:
Average speed in km / h = 2.7 km/h
Step-by-step explanation:
Given:
Total distance = 54,000 m
Total time = 72,000 sec
Find:
Average speed in km / h
Computation:
Average speed = Distance / Time
Average speed = 54,000 / 72,000
Average speed = 0.75 m/s
1 m/s = 3.6 km/h
So,
Average speed in km / h = 0.75 x 3.6
Average speed in km / h = 2.7 km/h
Answer:B
Step-by-step explanation:
Radius=8
Height=3
volume=π x radius x radius x height
volume=π x 8 x 8 x 3
volume=192π
Answer:
hopefully this helps? please try
The answer would be 19.25
