Answer:
I believe it's B
Step-by-step explanation:
B is the only one that includes all r and y 1 to 4 in both equations
Doubles each times
so 4/37 times 2/1=8/37 which is the next term
Volume a sphere: [4/3]π(r^3)
Space between the spheres = Volume of the larger sphere - Volume of the smaller sphere
= [4/3]π (R^3) - [4/3π](r^3) = [4/3]π(R^3 - r^3) = [4/3]π {(5cm)^3 - (4cm)^3} =
= 255.5 cm^3
Answer: 255.5 cm^3
Hey there!
The mean of the numbers is the <u>average</u>. To find the mean we will simply add all the numbers together, and divide them by the amount of numbers there are. Easy, peesy, lemon squeezy. Lets get started.
7 + 10 + 22 + 10 + 12 + 10 + 12 = 83
Now that we have added those altogether, we can divide them by the amount of numbers there are. The amount of numbers there are comes to a total of 7. Therefore...
83 divided by 7 = 11.857
Answer Choice B. 11.9 is your correct answer.
