Kunci Jawaban Matematika Kelas 5 SD Halaman 172: Menghitung Volume Tabung

r2 = 49

r =√49

= 7 cm

Diameter = 2 x r

= 2 x 7 cm

= 14 cm

Keliling alas tabung = π x d

= 22/7 x 14 cm

= 44 cm

3. Diketahui: V = 693 cm3, d = 7 cm

Ditanya: Tinggi tabung?

Jawab:

V = 1/4 x π x d x d x t

693 cm3 = 1/4 x 22/7 x 7 cm x 7 cm x t

693 cm3 = 77/4 x t
