Answer:
22.35 m/s
Step-by-step explanation:
The distance is always a positive unit, so distance traveled (d) = 15 miles
Time (t) = 0.3 hours
Time (t) = 0.3 * 60 = 18 minutes
(1 hour = 60 minutes)
Velocity (v) = ?
The formula of distance is: d = v*t
=> v = d/t = 15/18 = 0.83 miles/minute
we can also calculate velocity is meter/sec, for that
1 minute = 60 sec
=> 18 mins = 18*60 = 1080 sec
1 mile = 1609.34 meters
=> 15 miles = 15 * 1609.34 = 24,140 m
hence,
v = 24,140/1080 = 22.35 m/s
Answer:
Volume=2616.67
Step-by-step explanation:
V=1/3pi r squared height
V=1/3(3.14)(10)squ.(25)
V=1/3(3.14)(100)(25)
V=2616.66667
V=2616.67
Answer:
because the area expression can be rewritten as 
which equals 
Step-by-step explanation:
Area of the rectangle 
Since the length of a rectangle is 20 units more than its width.
The correct option is therefore 1.
Answer:
Area = 6647.610055 cm^2
Circumference = 289.02652413 cm
Step-by-step explanation:
Area of Circle: Area = π*r^2
Circumference: C = 2*π*r or π*d
Area = π * 46^2 = 6647.610055
Circumference = 2*π*46 = 289.02652413
