well first, the radius is half of the diameter, which is 6

Answer 14

and the height is 12

Answer 15

Answer 20

so far u r on the right track

Answer 21

Then you multiply 113.04 by the height divided by 3
or like this:

113.04*(12/3)

Answer 28

***I got 452.16***
ok, but they want
final answer to the nearest tenth..

the tenths place is the 1 to the right of the decimal point.
to round, look at the digit to its right (the 6) if that number is 5 or more (and it is) round the tenths digit up , otherwise leave it as it is.

can you round your answer to the nearest tenth?

Answer 29

Is 450 correct?

Answer 30

@jdoe0001

Answer 31

well 452.16 rounded up to the nearest "10th"

will be 0.16 rounds up to 0.20
thus 452.20

notice the 10 .... 16 .... 20

16 is closest to 20, than it's to 10
thus the rounding up goes to 20

Answer 32

so 20.1?

Answer 33

will be 0.16 rounds up to 0.20
thus 452.20

Answer 34

hmmm well .2 rather
.20 will be the nearest hundreth

so just 452.2
