No.3,4 dan 5 gimana caranya kk?

Jawab: 4.312 cm³

Penjelasan dengan langkah-langkah:

4. Volume

Tabung = π r² t

= 22/7 ( 14 cm : 2 )² 20 cm

= 22/7 x 7² cm x 20 cm

= 440/7 cm x 49 cm

= 3.080 cm³

Kerucut = 1/3 π r² t

= 1/3 x 22/7 x 7² cm x (44 –

20 ) cm

= 1/3 x 22/7 x 49 cm x 24

cm

= 154/3 cm x 24 cm

= 1.232 cm³

3.080 cm³ + 1.232 cm³

= 4.312 cm³
