t kerucut = [tex] \sqrt{ {s}^{2} - {r}^{2} } [/tex]
[tex] = \sqrt{ {25}^{2} - {7}^{2} } [/tex]
[tex] = \sqrt{625 - 49} [/tex]
[tex] = \sqrt{576} [/tex]
[tex] = 24[/tex]
V gabungan = V kerucut + V bola
= (⅓ πr²t) + (½ x ⁴⁄₃πr³)
= (⅓ x 22/7 x 7 x 7 x 24) + (½ x ⁴⁄₃ x 22/7 x 7 x 7 x 7)
= (22 x 7 x 8) + (4⁄₃ x 11 x 7 x 7)
= 1232 + 718,66
= 1950,67 cm³
