Area of a sphere formula = 4/3 pi x r^3
4/3 pi x 4^3 x 0.075 = 20.106
20.106 rounds to 20 to the nearest pound
These are vertical angles and if one side is 150 degrees then the other is also 150 degrees so 3x-15=150 so the answer is x =55
The answer would be: 0.5L
This question can be solved using the ideal gas formula PV=nRT where
P= pressure
V= volume
n= number of molecule
R= constant
T= temperature
In this question, the temperature and number of the particle are not changed. The pressure is changed to twice amount. Since the pressure is inversely related to the volume, the volume should become half of the original.
PV=nRT
V=nRT/P
V1/V2= (nRT/P1)/(nRT/P2)
V1/V2= (1/270)/(1/540)
V1/V2= (1/1)/(1/2)
V1/V2 = 2
V1= 2V2
1L= 2V2
V2= 1/2 L
