Hello from MrBillDoesMath!
Answer:
2035.8 (approximately)
Discussion:
The volume of a cone or radius r and height h is given by the formula:
Volume = (1/3) Pi * r^2 * h. In our case this is:
V = (1/3) Pi * (18)^2 * 6
=(1/3) Pi * 324 * 6 => 324/3 = 108
= 108 * 6 Pi => 108 *6 = 648
= 648 * Pi => approximating Pi by 3.14
= 648 * 3.14
= 2035.8 (approximately)
Thank you,

The speed of plane 1 will be 300 miles/sec and that of plane 2 will be 600 miles/sec.
We have two planes flying in opposite directions to each other.
We have to determine how fast was the each plane flying.
<h3>What is the formula to calculate the distance covered by the object moving with speed - x m/s in time - t s ?</h3>
The formula to calculate the distance travelled will be -
distance = speed x time = (
t) meters
According to the question -
Let us assume that the speed of plane 1 = v miles/sec.
Then, the speed of plane 2 will be = 2v miles/sec.
Distance covered by plane 1 in 3 hours will be = 3v miles.
Distance covered by plane 2 in 3 hours will be = 3 x (2v) miles = 6v miles.
Since they are 2700 miles apart after three hours, therefore -
3v + 6v = 2700
9v = 2700
v = 300 miles/sec
Hence, the speed of plane 1 will be 300 miles/sec and that of plane 2 will be = 2v = 2 x 300 = 600 miles/sec.

Answer:
Step-by-step explanation:
In order to find the slope, subtract -7 and -7, which is -7-(-7)=-7+7=0
Then subtract 7 and -2, which is 7-(-2) = 7+2=9
Divide 0 and 9 which equals 0
the slope is 0
