Step-by-step explanation:

Hi.

Here is your answer---

Given---

Outer Radius(R) = 3 cm.

Inner Radius(r) = 1 cm.

Length(h) = 6 cm.

Using the Formula,

   Volume of Material(or Metal) = π h( R² - r²)

                                                 = (22/7) × 6 × (3² - 1²)

                                                 = (22/7) × 6 × ( 9 - 1)

                                                 = (22/7) × 6 × 8

                                                 = 1056 cm³.

Thus, the volume of the metals in th pipe is 1056 cm³.
