Perhatikan gambar! Volune bangun berikut adalah...

Bangun Ruang Sisi Lengkung

V tabung = π x r x r x t
= 22/7 x (14/2) x (14/2) x (12 - 14/2)
= 22/7 x 7 x 7 x (12 - 7)
= 22 x 7 x 5
= 770 cm^3

V 1/2 bola = 1/2 x 4/3 x π x r x r x r
= 2/3 x 22/7 x 7 x 7 x 7
= 2/3 x 22 x 7 x 7
= 2156/3
= 718,67 cm^3

V gabungan = V tabung + V 1/2 bola
= 770 + 718,67
= 1488,67 cm^3 (A).

*semoga membantu. sukses selalu ^_^

Volume 1/2 bola
= 1/2 x 4/3 x phi x r^3
= 1/2 x 4/3 x 22/7 x (14/2) x (14/2) x (14/2)
= 2/3 x 22/7 x 7 x 7 x 7
= 2/3 x 1078
= 718,67 cm^3

Volume tabung
= phi x r² x t
= 22/7 x (14/2) x (14/2) x (12 - 14/2)
= 22/7 x 7 x 7 x (12 - 7)
= 154 x 5
= 770 cm^3

Volume gabungan
= 718,67 + 770
= 1488,67 cm^3
