Question

Volume/area problem;
picture attached below :)

Answer 1

A.

Answer 2

\[\Large ratio=\frac{volume}{area} = \frac{\frac43 \pi r^3}{\pi r^2}\]

Answer 3

@saifoo.khan , I typed it in my calculator and got \[\frac{ 4 }{ 3\pi ^{2}r^5 }\]

Answer 4

Nope. Try again. Try cancelling out things.

Answer 5

thats not right u have to divide 4/3πr3 byπr2

Answer 6

\[\frac{ 4 }{ 3r^5 }\] ?

Answer 7

now tell me what all is going to cancel out

Answer 8

But when we divide , we subtract exponents.., so would it be 4/3r not 4/3r^5 ?

Answer 9

thats right

Answer 10

u got it

Answer 11

@saifoo.khan

Answer 12

43πr3/1*1/πr2 now try to solve it

Answer 13

try to cancel some things frm the numerator and the denominator

Answer 14

Yes. A is right.

Answer 15

Yay.
