Answer:
r = 3m
Step-by-step explanation:
Formula for the volume of a sphere: V =
We want to find the radius so we use algebra to rearrange the equation to make the radius (r) the subject of the equation
Divide both sides by
=
Divide both sides by
=
Take the cube root of both sides
= r
Substitute V = 36 into the equation
r =
Expand the bracket
r =
Divide 108 by 4 (For this, the two in the numerator and denominator cancel each other out, and you only need to divide 108/4)
r =
The cube root of 27 is 3, because = 3 x 3 x 3 = 27
r = 3
