Answer:
0.8 hours
Step-by-step explanation:
From the question;
- Speed of Min-jun is 27 miles per hour
- Distance covered is 21 miles
We need to determine the time he takes to cover the distance given;
We need to know that;
Speed = Distance ÷ time
Rearranging the formula;
time = Distance ÷ speed
Thus;
Time = 21 miles ÷ 27 miles per hour
= 7/9 hours
= 0.8 hours
Thus, he took 0.8 hours to cover the distance covered
Answer:
true
Step-by-step explanation:
V = ⁴/₃πr³
V = ⁴/₃(3.14)(6)³
V = ⁴/₃(3.14)(216)
V = ⁴/₃(678.24)
V = 904.23cm³
It is equal to 288πcm³.
