Answer 1

@dude So we just apply the same principle as the first one?

Answer 2

Yes

Answer 3

Well, find the radius first
Then solve for the volume

Answer 4

4/3 =r3 Thats how its written, am I right? I forgot XD

Answer 5

the volume?

Answer 6

Sorry, I forgot how its written to solve it

Answer 7

Wait, was that it?

Answer 8

\[V=\frac43\pi r^3\]

Answer 9

Ahh okay forgot about the V

Answer 10

972pi

Answer 11

Did you find the radius first?

Answer 12

The radius was 9, right?

Answer 13

9 inches on the basketball

Answer 14

Nooo, that is the diameter. The diameter is always the length across the sphere

Answer 15

How do I find the raduis?

Answer 16

Divide the diameter by 2

Answer 17

9 divided by 2? It equals 4.5

Answer 18

Yes, and then you substitute that into the volume equation

Answer 19

4.5^3?

Answer 20

That would make the answer B, wouldn't it?
