Here's the solution,
the volume of the given figure is :
=》
volume of pyramid :
=》
=》
=》
=》
volume of pyramid = 40 cm³
now, volume of rectangular prism :
=》
=》
=》
volume of rectangular prism = 40 cm³
volume of composite figure = 40 + 40
=》80 cm³
The 3-D shape would be created if the figure was rotated around the x-axis is a cone
<h3>What are 3-D shapes?</h3>3-D shapes (short form of 3-Dimensional shapes) are shapes that have width, length and height
<h3>How to determine the 3-D shape?</h3>The coordinates are given as:
(0, 0), (-3, -4) and (-3, 0)
When the above coordinates are plotted on a coordinate plane and the points are connected;
We can see that the points form a right-triangle
See attachment for the shape
As a general rule
Rotating a right-triangle across the x-axis would form a cone
Hence, the 3-D shape would be created if the figure was rotated around the x-axis is a cone
