Question

is anyone familiar with volumes? if so can you help with one question

Answer 1

The candy is a sphere. There's a smaller sphere in the middle surrounded by a shell. To find the volume of the outer shell, all you need to do is subtract the volume of the small inner sphere from the volume of the entire candy!

Answer 2

you can use the formula
$$
\Large V=\pi~ (r_{outer}^2- r_{inner}^2)

$$

Answer 3

okay so what is pi?

Answer 4

3.14 right

Answer 5

Pi is a constant. You can use 3.14.

Answer 6

okay so 6-9 x3.14 =-22.26

Answer 7

is that correct?

Answer 8

no, you did r you need to do r^2
always positive

Answer 9

do i have to do r^2 to both of them?

Answer 10

yes
the volume of a sphere is

Answer 11

9156.24

Answer 12

so its going to be 659,249.28?

Answer 13

6^3 x 9^3 =157,464 x 3.14=494,436.96 x 4 divide 3 and i got 659,249.28

Answer 14

@perl how did you arrive at that formula?
