Answer:
28 bees per square feet.
Step-by-step explanation:
The radius of the circle is 3 feet.
Therefore, area of the circle is equal to square feet.
Now, in this area of 28.28 square feet, there live 800 bees.
Therefore, the population density of bees per square foot will be bees per square foot ≈ 28 bees per square feet. (Answer)
Answer:
The density is 0.2g/mL^2.
Step-by-step explanation:
- Use the formula: D=
(where v=volume, and m=mass). The mass of the liquid is 6g. The volume of the liquid is 30mL.
- To determine density, insert the values into the formula (
).
- Divide: 6g/30mL= 0.2g/mL^2
