Question

tolong aku kak plisss​

Answer 1

Penjelasan dengan langkah-langkah:

5. v = p×l×t

= 28×28×20

= 15680CM

6. V = π×r×r×t

= 3,14×25×7

=549,5CM

7. V = P×L×T

= 7×6×5

=210 DM

Answer 2

Penjelasan dengan langkah-langkah:

5.Volume balok

=p×l×t

=28×28×20

=15.680 cm³

Volume tabung

=πr²t

=22/7×14×14×20

=12.320 cm³

Volume gabungan

=volume balok+Volume tabung

=15.680 cm³+12.320 cm³

=28.000 cm³

6.Volume tabung 1

=πr²t.

=3,14×5×5×7

=549,5 cm³

Volume tabung 2

=πr²t

=3,14×10×10×14

=4.396 cm³.

volume gabung

=549,5+4.396

=4.945,5 cm³

7. Volume balok

=p×l×t

=7×6×5

=210 dm³

Volume Tabung

=πr²t

=22/7×1,75×1,75×3

=28,875 dm³

volume gabung

=volume balok+volume tabung

=210 dm³+28,875 dm³

=238,875 dm³
