Answer:
The radius is 1/6 m
Step-by-step explanation:
The volume of a sphere is given by
V = 4/3 pi r^3
1/162 * pi = 4/3 pi r^3
Divide each side by pi
1/162 = 4/3 r^3
Multiply each side by 3/4
3/4 *1/162 =3/4* 4/3 r^3
1/216 = r^3
Take the cube root of each side
(1/216)^ 1/3 = (r^3)^1/3
1/6 = r
The radius is 1/6 m
