Rumus vol tabung adl tinggi x luas lingkaran alas 4710 = a (tinggi) x pi r² 4710= a x 3,14 x 10 x 10 a = 4710 / 314 a = 15 tingginya 15 cm
Verified answer
Volume = 4.710D = 20
r = D/2
= 20/2
= 10
V = π.r².t
4.710 = 3,14 x 10² x t
4.710 = 3,14 x 100 x t
4.710 = 314 x t
t = 4.710 : 314
t = 15
4710 = a (tinggi) x pi r²
4710= a x 3,14 x 10 x 10
a = 4710 / 314
a = 15
