Height of a Right Cone formula |
||
| \( h \;=\; 3 \cdot \dfrac{ V }{ \pi \cdot r^2 } \) | ||
| Symbol | English | Metric |
| \( h \) = height | \( in \) | \( mm \) |
| \( r \) = radius | \( in \) | \( mm \) |
| \( V \) = volume | \( in^3 \) | \( mm^3 \) |
- Right cone (a three-dimensional figure) has a circle base with the apex alligned at 90° above the center of the base.
- 1 base
