Question

If the volume of a sphere is 36 cubic units, what is the radius? How would I write the equation to solve this

Answer 1

Ur equation would be
36= 4/3*3.14*r^3

Answer 2

\[\frac{ 4 }{ 3 }\pi r ^{3}=36\]
\[[\frac{ 3 }{ 4\pi }36]^{1/3}=r\]

Answer 3

So what would my answer be? I'm confused

Answer 4

use the equation I have setup and solve for r

Answer 5

Is the radius 9pi?

Answer 6

not quite a number to a power can also be thought of as the cube root of a number

Answer 7

a number to the 1/3 specifically

Answer 8

So what would the next step be?

Answer 10

use this equation and this will be your final answer
\[r=\sqrt[3]{\frac{ 3(36) }{ 4\pi }}\]

Answer 11

9 units?

Answer 13

@elementwielder would 9 units be my answer?

Answer 14

?

Answer 15

one second...

Answer 16

ok

Answer 17

no i got r= 2.04835...

Answer 18

okay thank you
