bisa bantu gak.. saya bingung caranya nih.. ?

r = ½ d = 7 cm

T kerucut =
[tex] t = \sqrt{s^{2} - r ^{2}} \\ t = \sqrt{25^{2} - 7^{2} } \\ t = \sqrt{625 - 49} \\ t = \sqrt{576} \\ t = 24[/tex]
V kerucut = ⅓ × π × r² × t
= 1/3 × 22/7 × 7² × 24
= 1/3 × 22 × 7 × 24
= 22 × 7 × 8
= 1.232 cm³

V setengah bola = 4/3 × π × r³ × 1/2
= 4/3 × 22/7 × 7³ × 1/2
= 4/3 × 22 × 7² × 1/2
= 4/6 × 22 × 49
= 4/6 × 1.078
= 718,66 cm³

V total = V kerucut + V setengah bola
= 1.232 + 718,666
= 1.950,66 cm³

maaf kalo ada salah
