Answer:
In order to solve this problem, we need to know the volume of a sphere.
The volume of a sphere is (4/3)pir^3
In this case our r value, or radius, is 30cm.
If we plug in 30cm to the equation like so:
(4/3)pi(30)^3
The answer is 113097 cm^3 of air

Answer:
5 hours and 40 minutes would be class
Step-by-step explanation:
We know that the total time is 7 hours, which in minutes would be:
7 * 60 = 420
420 minutes would be class, now, we subtract the other times that are not to be in class and it would be:
420 - 30 - 50 = 340
So we could say that in class it takes 340 minutes, and if we spend hours it would be:
340/60 = 5.67 hours or also 5 hours and 40 minutes would be class.
X + 8 < 14 |subtract 8 from both sides
x < 6 ⇒ x ∈ (-∞; 6)
