Answer:
<u>The radius of the cylinder and sphere is 2.48 cm and the volume of the sphere is 64 cm³</u>
Step-by-step explanation:
Let's review the information given to us to answer the question correctly:
Volume of a cylinder = π * r² * h
π * r² * h = 48
r² * h = 48/3.1416
r² * h = 15.28
r = 2.48 cm, h = 2.48 cm
Now, we can calculate the volume of the sphere this way:
Volume of the sphere = 4/3 * π * r³
Volume of the sphere = 4/3 * π * 2.48³
Volume of the sphere = 4/3 * π * 15.28
Volume of the sphere = 1.33 * 3.1416 * 15.28
<u>Volume of the sphere = 64 cm³</u>
Answer:
tha answer to the question is B. 2
Answer:
-16
Step-by-step explanation:
When adding a negative and a positive number, you need to keep in mind that your are essentially adding.
so if I have a number line
-24, -23, -22, -21, -20, -19, -18, -17, -16, -15, -14,,,,
you will start at -24 and will go up the number line (to the right) 8 times and that should get you your answer.
Answer:7 and 3/16
Step-by-step explanation: 2+1+3=6. 3/4 + 1/8 +5/16 = 1 and 3/16. 6 + 1 and 3/ 16= 7 and 3/16
Answer:
10 experiments
Step-by-step explanation:
Given:
Amount of substance A = ![\frac{1}{2}\textrm{ g}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%5Ctextrm%7B%20g%7D)
Amount of substance B =
Total amount of mixture = ![\frac{1}{2}\textrm{ g}+\frac{3}{4}\textrm{ g}=\frac{5}{4}\textrm{ g}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%5Ctextrm%7B%20g%7D%2B%5Cfrac%7B3%7D%7B4%7D%5Ctextrm%7B%20g%7D%3D%5Cfrac%7B5%7D%7B4%7D%5Ctextrm%7B%20g%7D)
Now, amount used for each experiment = ![\frac{1}{8}\textrm{ g}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B8%7D%5Ctextrm%7B%20g%7D)
So, number of experiments conducted = ![\frac{\textrm{Total amount of mixture}}{\textrm{Amount used for each experiment}}=\frac{\frac{5}{4} }{\frac{1}{8} } =\frac{5}{4}\times 8=10](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctextrm%7BTotal%20amount%20of%20mixture%7D%7D%7B%5Ctextrm%7BAmount%20used%20for%20each%20experiment%7D%7D%3D%5Cfrac%7B%5Cfrac%7B5%7D%7B4%7D%20%7D%7B%5Cfrac%7B1%7D%7B8%7D%20%7D%20%3D%5Cfrac%7B5%7D%7B4%7D%5Ctimes%208%3D10)
Therefore, the number of experiments conducted are 10.
