Penjelasan dengan langkah-langkah:
a. Rumus tabung = π x r² x t
= 22/7 x 7² x 12
= 22/7 x 49 x 12
= 22/7 x 588
= 1.848 cm³
b. Rumus = π x r² x t
= 3,14 x 15² x 22
= 3,14 x 225 x 22
= 3,14 x 4.950
= 15.543 cm³
c. Rumus = π x r² x t
= 22/7 x (28:2)² x 10
= 22/7 x 14² x 10
= 22/7 x 196 x 10
= 22/7 x 1.960
= 6.160 cm³
d. Rumus = π x r² x t
= 22/7 x (7:2)² x 30
= 22/7 x 3,5² x 30
= 22/7 x 12,25 x 30
= 22/7 x 367,5
= 1.155 cm³
e. Rumus = π x r² x t
= 3,14 x (10:2)² x 5
= 3,14 x 5² x 5
= 3,14 x 25 x 5
= 3,14 x 125
= 392,5 cm³

Jawaban:
rumus volume tabung = πr² × t
Penjelasan dengan langkah-langkah:
1. = 22/7 × 7×7
= 22/7 × 49
= 154
= 154 × 12
= 1.848 cm³
2. r = 28 : 2 = 14
= 22/7 × 14 × 14
= 22/7 × 196
= 616
= 616 × 10
= 6.160 cm³
3. r = 10:2 = 5
= 3,14 × 5 × 5
= 3,14 × 25
= 78.5
= 78.5 × 5
= 392.5 cm³
4. = 3,14 × 15 × 15
= 3,14 × 225
= 706.5 × 22
= 15.543 cm³
5. r = 7 : 2 = 3.5
= 22/7 × 3.5 × 3.5
= 22/7 × 12.25
= 38.5 × 30
= 1.155 cm³
