Answer 1

The volume of the spherical piece is 288.55 cm³.

Solution:

Diameter of the sphere = 8.2 cm

Radius of the sphere = 8.2 ÷ 2 = 4.1 cm

The value of π = 3.14

Volume of the sphere $=\frac{4}{3} \pi r^{3}$

                                    $=\frac{4}{3} \times 3.14 \times(4.1)^{3}$

                                    $=\frac{4}{3} \times 3.14 \times68.921$

                                    = 288.55 cm³

The volume of the spherical piece is 288.55 cm³.
