Answer:
9.4 yds
Step-by-step explanation:
The formula for the perimeter (circumference) of a circle is C = dπ. Here d = 6 yds, and so the circumference of the circle is (3.14)(6 yds) = 18.8 yds.
The semicircle's perimeter is half that: 9.4 yds
When x=1, y is 3
When x=2, y is 1
When x=3, y is -1
When x=4, y is -3
When x=5, y is -5
Well let's see.
m/s
27000 km/hour = (27000 km/hr) * (1000m/km] * [1 hour / 3600 sec] = 2700 m/s
miles / hour
27000 km/hour * [1 mile/1.6 km] = 16875 miles / hour (that's fast)
meters / hour
27000 km/hour * 1000 m/km = 27 000 000 m/hour
Miles / Second
27000 km/hour * [1 mile / 1.6km]*[1 hour/3600 sec] = 4.6875 miles / second
Km / second
27000 km/hour [1 hour / 3600 sec] = 7.5 km/second.
