The volume of air surrounding the cone and inside the cylinder will be the difference of the volume of cylinder and the cone. 

So,

Volume of air = Volume of cylinder - Volume of cone

= \pi r^{2}h- \frac{1}{3} \pi  r^{2}h \\  \\ 
=3.14(5)^{2}(16)- \frac{1}{3}(3.14) (4)^{2}(12) \\  \\ 
=1055.04

Thus, the volume of the air surrounding the cone and inside the cylinder will be 1055.04 cubic centimeter

Volume of air = volume of cylinder - volume of cone

cylinder = pi * r * r * h
cone  = pi * r * r * h/3

substitute the values;
The volume of air is equal to 1055.05cu.cm

A sofa is selling for $422.50 after a 35% discount . What was the original price for the sofa ?
lana [24]
Let, the original price = x
Then, it's 100 - 35 = 65% = 422.50

So, x * 0.65 = 422.50
x = 422.50 / 0.65
x = 650

In short, Your Answer would be $650

Hope this helps!

The graph below shows the distances, in miles, that a dragonfly can travel in a certain number of hours:
Y_Kistochka [10]
Ur independent variable is ur x values....ur dependent variable is ur y values..so if hrs are on the x axis, then ur independent values are ur hrs (or time)....and ur dependent values are ur distance.

(0,0),(2,50)
slope = (50 - 0) / (2 - 0) = 50/2 = 25

y = mx + b
slope(m) = 25
and since u have point (0,0), ur y int (b) = 0
so ur equation is y = 25x + 0 which is written as y = 25x...which is basically saying that he travels 25 miles per hr

how far will he travel in 24 hrs.....so sub in 24 for x
y = 25(24)
y = 600 miles

in summary : The dependent variable is distance, the equation is y = 25x and the dragonfly will fly 600 miles.

Tamara paid $3.00 for cartons of milk. Teo paid $3.75 for a different number of cartons at the same store. How much is one carto
Rashid [163]
1- Price of each carton:
Since they both bought different number of cartons of milk from the same store, we can simply find the price of one carton from the difference between what they both paid.

Since Tamara paid 3$ and Toe paid 3.75$, we can simply say that one carton of milk costs 0.75$ and that Toe bought one carton more than Tamra.

2- How many cartons each bought:
Tamra bought : 3 / 0.75 = 4 cartons
Toe bought : 3.75 / 0.75 = 5 cartons
