Question

Mohon bantuan nya ya :v

Answer 1

V. tabung = π x r x r x t
= ( 22/7 ) x 7 x 7 x ( 12 - 7 )
= 22 x 7 x 5
= 154 x 5
= 770 cm³

V. ½ bola = ½ x ( 4/3 ) x π x r x r x r
= ⅔ x ( 22/7 ) x 7 x 7 x 7
= ⅔ x 22 x 7 x 7
= 44 x 49 / 3
= 2.156 / 3
= 718,67 cm³

V. total = V. tabung + V. bola
= 770 + 718,67
= 1.488,67 cm³ -A-
