B is the correct answer

Answer:

B; or 8.5

Step-by-step explanation:

Mean is also known for average of the numbers.

To find the mean simply add all the numbers together and divide by the quantity of the numbers given. So first add up "8 + 10 + 6 + 4 + 12 + 6 + 8 + 14" this all equals to 68 and since the total quantity of the numbers given is 8, so divide 68 by 8 which gives the answer as 8.5.

Hope this helps!

How do you find the volume of a cylinder??

Answers

Answer:

(super high school level genius way)The formula for the volume of a cylinder is V=B h or V=πr2h . The radius of the cylinder is 8 cm and the height is 15 cm. Substitute 8 for r and 15 for h in the formula V=πr2h .

(super high school easy way) In math, volume is the amount of space in a certain 3D object. For instance, a fish tank has 3 feet in length, 1 foot in width and two feet in height. To find the volume, you multiply length times width times height, which is 3x1x2, which equals six. So the volume of the fish tank is 6 cubic feet.

Answers

Answer:

so for the first problem, you round to ten since the one place is a nine. for the second one, your round to 67 since the decimal point is 9. for the third one, you round to 100 since it's 94 and anything above 50 rounds to 100. fo the fourth one round to 9 since the decimal point is a 2. for the fifth one you round to 40 since the one's place is a well...1.

Step-by-step explanation:

okay so as we know when the number is over 5 we round up. so for the sixth problem we can see it says we round to nearest whole number meaning the ones place. now when we round we look to the number on the right. in this case its the one on the other side of the decimal point. Which if we see is a 4, which is less than 5 so orund down to 9.
