**Answer:**

**Volume of gumball without including its hollow core is 48347.6 cubic mm.**

**Step-by-step explanation:**

Given:

Diameter of Gumball = 66 mm

Since radius is half of diameter.

Radius of gumball =

Now We will first find the Volume of Gumball.

To find the Volume of Gumball we will use volume of sphere which is given as;

Volume of Sphere =

Now Volume of Gumball =

Also Given

Diameter of gumball's spherical hollow core = 58 mm

Since radius is half of diameter.

Radius of gumball's spherical hollow core =

Now We will find the Volume of gumball's spherical hollow core.

Volume of Sphere =

So Volume of gumball's spherical hollow core =

Now We need to find volume of the gumball without including its hollow core.

**So, To find volume of the gumball without including its hollow core we would Subtract Volume of gumball spherical hollow core from Volume of Gumball.**

volume of the gumball without including its hollow core = Volume of Gumball - Volume of gumball's spherical hollow core =

Rounding to nearest tenth we get;

volume of the gumball without including its hollow core =

**Hence Volume of gumball without including its hollow core is 48347.6 cubic mm.**
