r

=

3

c

m

Explanation:

The volume of the given sphere is

36

π

c

m

3

The volume of every sphere is:

V

=

4

π

⋅

r

3

3

So we can equate the two volumes:

4

π

⋅

r

3

3

=

36

π

c

m

3

Multiply both sides by

3

:

4

π

⋅

r

3

=

108

π

c

m

3

and divide both by

4

π

:

r

3

=

27

c

m

3

r

=

3

c

m
