To calculate the volume of a cylinder, you can use the formula:
\[ V = \pi r^2 h \]
where \( V \) is the volume, \( r \) is the radius, and \( h \) is the height.
Given:
- Height (\( h \)) = 20 cm
- Radius (\( r \)) = 5 cm
Now, plug the values into the formula:
\[ V = \pi (5)^2 (20) \]
Calculating \( (5)^2 \):
\[ (5)^2 = 25 \]
Now multiply by the height:
\[ V = \pi \times 25 \times 20 \]
Now calculate \( 25 \times 20 \):
\[ 25 \times 20 = 500 \]
So, the volume is:
\[ V = 500\pi \text{ cm}^3 \]
Thus, the answer is:
500π cm³ (or 500 pi cm cubed)
