The equation for volume of a sphere is:
Volume = 4/3 * PI * r^3
r is the radius = 1 inch
Volume is given as 4 cubic inches per second increase.
Given: dv/dt = 4 cubic inches per second.
Need to find dr/dt
Formula for volume of a sphere is: V = 4/3 * π * r^3
so now we have:
4 in^3 = 4 * π *1^2
Divide both sides by 4 * π *1^2
4 in^3 / 4π = 1/π inch per second.
The answer is 1/π inch per second ( exact answer)
or as a decimal: 0.3183 ( round as needed).
Answer: see below
<u>Step-by-step explanation:</u>
The "point" on the inequality symbol points to the smaller number
- < is the "less than" inequality symbol
- > is the "greater than" inequality symbol
- = is the "equal" symbol
18) 3 = 3
20) 
22) 0.8 = 4/5 Note: 4÷5 is 0.8
26) 0.075 < 0.39
28) -5.2 < -4.8
30) 0.4 > 
32) 
14x2=28
28 divided by 3 is 9.3
the answer is 9.3
According to the information in the nutritional table, it can be inferred that the amount of milligrams of sodium that we should consume during the rest of the day must be less than 2,175mg,
<h3>How to calculate the amount of sodium we can consume?</h3>
To calculate the amount of sodium that we can consume during the rest of the day after breakfast, we must subtract the value of sodium consumed to the amount of total sodium that we want to ingest as shown below:
According to the above, it can be inferred that after consuming the cereal bar at breakfast, we should consume an amount less than or equal to 2,175mg of sodium in the other meals of the day (lunch, dinner and snacks).
