K0 ganzer Kegel, K1 Kegel in h/4 geschnitten, K Kegel in 3/4h geschnitten
\(K0 \, := \, \frac{1}{3} \; h_0 \; r_0^{2} \; \pi \)
\(K1 \, := \, \frac{1}{3} \; \left(\frac{3}{4} \; r_0 \right)^{2} \; \pi \; \frac{3}{4} \; h_0 = K1 \, = \, \frac{27}{64} \; \frac{1}{3} \; h_0 \; r_0^{2} \; \pi = \, \frac{27}{64} \; K0 \)
\(K2 \, := \, \frac{1}{3} \; \left(\frac{1}{4} \; r_0 \right)^{2} \; \pi \; \frac{1}{4} \; h_0 = \, \frac{1}{64} \; \frac{1}{3} \; h_0 \; r_0^{2} \; \pi = \, \frac{1}{64} \; K0 \)
