The answer for c would be 805
V= pi * r^2 * h
471 = 3.14 * r^2 *6
471 = 18.84 * r^2
25 = r^2
Sqrt25 = r
5 = r
D= 2*5
D= 10in
Answer:
- jet in still air: 712 mi/h
- jetstream rate: 50 mi/h
Step-by-step explanation:
The relation between speed, time, and distance is ...
speed = distance/time
Against the wind, the speed is ...
(3310 mi)/(5 h) = 662 mi/h
With the wind, the speed is ...
(3810 mi)/(5 h) = 762 mi/h
The jet stream adds to the speed in one direction, and subtracts in the other direction, so the difference in travel speeds is twice the speed of the jet stream:
(762 mi/h -662 mi/h)/2 = jet stream speed = 50 mi/h
__
The speed of the plane is the average of the two speeds, or the sum of jet stream speed and the lower speed, or the difference of the higher speed and the jet stream speed. Any of these calculations will give the plane's speed in still air:
(762+662)/2 = 662 +50 = 762 -50 = 712 . . . mi/h
Answer: below
Step-by-step explanation:
First, plot a point on (0,5). That is the y-intercept. Then count 1 unit to the right then 3 units up. Plot a point there and repeat until you have no more space. Then go from the y-intercept and count 1 unit to the left then 3 units down. Repeat and then draw a line through all the points you have plotted.
