Volume bangun disamping adalah…cm³​

Jawab:

Volume = 39.424 cm³

Penjelasan dengan langkah-langkah:

Diketahui:

r = 14 cm

t = 64 cm

Ditanya:

V?

Jawab:

V = L alas x t

V = πr²t

V = 22/7 x (14 cm)² x 64 cm

V = 616 cm² x 64 cm

V = 39.424 cm³

Jawaban:

r = 14 cm

t = 64 cm

Luas Selimut Tabung

= 2πr x t

= 2 x 22/7 x 14 x 64

= 44 x 2 x 64

= 5.632 cm²

Luas Permukaan tabung

= 2πr (r + t)

= 2 x 22/7 x 14 (14 + 64)

= 88 (78)

= 6.864 cm²

Volume tabung

= πr² x t

= 22/7 x 14² x 64

= 22 x 28 x 64

= 39.424 cm³
