Diketahui :

- ½ Bola :
• r = 7 cm

- Kerucut :
• r = 7 cm
• t = 10 cm

Ditanya :
- V Total

VB = 2/3 x πr³
VB = 2/3 x 22/7 x 7 x 7 x 7
VB = 2/3 x 22 x 7 x 7
VB = 2/3 x 154 x 7
VB = 2/3 x 1078
VB = 718,7 cm³

VK = ⅓ x La x t
VK = ⅓ x 22/7 x 7 x 7 x 10
VK = ⅓ x 22 x 7 x 10
VK = ⅓ x 154 x 10
VK = ⅓ x 1540
VK = 513,3 cm³

V Total = 718,7 + 513,3
V Total = 1232 cm³

Jawaban : 1232 cm³ (B)
