A net is a pattern made when the surface of a 3-D figure is laid out flat, showing each face of the figure. A solid may have different nets.
Practice makes perfect
Let's consider the given 3-D figure.
A net is a pattern made when the surface of a 3-D figure is laid out flat showing each face of the figure. In the given figure, we can see that the cylinder has a radius of 4 cm. Therefore, the length of the lateral face is the same as the circumference of the circle, which is given by:
C=2Ď€ r
Let's substitute 4 for r in the above equation to find the length of the lateral face.
