Answer 1

$\text{Volume of the object = 544 cm}^3$

Explanation:

The object consists of a cylinder and a sphere

To get the volume of the object, we will find the volume of the cylinder and the sphere and sum it up

$\text{Volume of a cylinder = }\pi r^{2}h$

height = 6 cm

diameter = 8 cm

radius = diameter/2 = 8/2

radius = 4 cm

π = 3

$\begin{gathered} \text{Volume of the cylinder = 3 }\times4^2\times6 \\ Volume\text{ }of\text{ }the\text{ }cylinder=288cm^3\text{ } \end{gathered}$$\text{Volume of a sphere = }\frac{4}{3}\pi r^3$

radius = 4cm

π = 3

$\begin{gathered} \text{Volume of the sphere = }\frac{4}{3}\times3\times4^3 \\ \text{Volume of the sphere = 256 cm}^3 \end{gathered}$

Volume of the object = Volume of the cylinder + Volume of the sphere

$\begin{gathered} \text{Volume of the object = 288 + 256} \\ \text{Volume of the object = 544 cm}^3 \end{gathered}$
