The speed of the car is 96 km/h
Step-by-step explanation:
Your question, trasnlated into English, is teh following
"The passenger car traveled 120 km in 75 minutes. at what speed he moved (km / h) "
We use the definition of speed
Speed = Distance / time
Distance = 120 km
time = 75 minutes = 1.25 h
Speed = 120 km / 1.25 h
Speed = 96 km/h
The speed of the car is 96 km/h
The diameter is 6. Explanation:
radius: 3.14r^2
28.26=3.14r^2
28.26/3.14=r^2
r^2=9
r=3
and we know that diameter is two times the radius so:
3*2=6
diameter equals 6.
if you want to check it plug back in:
3^2 * 3.14 = 28.26
hope this helped :)
