A.
133 in3

B.
177 in3

C.
310 in3

D.
931 in3


I think it is D. but i'm not sure

Answer 1

Hmm..

Answer 2

I Got D.. But I'm Not The Smartest Person Out There :p

Answer 3

I pretty sure its A

Answer 4

thats what i thought, however they told me to use the formulas V=s^3 or 1/3 Bh not really sure ??

Answer 5

Hold Up.. I'mma Check

Answer 6

i got D somehow

Answer 7

can you please explain how, ?

Answer 8

Yea I Got A..

Answer 9

Accoroding to the\[2 \pi \times r \times h= 2\pi \times3.5\times19=133\]

Answer 10

can you use the formulas i gave you and get the same answer ?

Answer 11

what formula?

Answer 12

V=S^3 , or 1/3Bh

Answer 13

nothin ?

Answer 14

Do you got it

Answer 15

It should be 310 because its approximately 310.33 then just round you get 310

Answer 16

so C.

Answer 17

First find the base area\[B=s ^{2}=7^{2}\] Then the equation to find volume \[V=\frac{ 1 }{ 3 }Bh\]\[=\frac{ 1 }{ 3 }\times49\times19\]\[=310.333333333\]Then you round so it will be\[310\]
