Question

A cone has its radius(R) equal to its height. What is the volume of its frustum if the smaller cone's radius is r? ​

Answer 1

Answer:

Formula of cone frustrum

$\frac{1}{3} \times \pi \times h \times ( {r1}^{2} + {r2}^{2} + (r1 \times r2)) \\ = > we \: have \: r1 = h \\ = > r2 = r \\ = > put \: in \: eqution \\ \\ = > \frac{1}{3} \times \pi \:h \times ( {h}^{2} + {r}^{2} + hr) \\ = > \frac{\pi \: h}{3} \times ( {h}^{2} + {r}^{2} + hr)$
