tolong bantu ya kak pakai cara nomor 4 ,6 ,8 ,dan 10

4)
V = 1/2 × a × ts × tp
V = 1/2 × 20 × 4 × 12
V = 480 cm^3

6)
V = 1/3 × 1/4 × phi × d^2 × t
V = 1/3 × 1/4 × 22/7 × 14^2 × 15
V = 1/3 × 1/4 × 22/7 × 196 × 15
V = 770 cm^3

8)
V = 1/3 × La × t
V = 1/3 × 7^2 × 10
V = 1/3 × 49 × 10
V = 163,33 cm^3

10)
V = 1/3 × La × t
V = 1/3 × 9^2 × 6
V = 1/3 × 81 × 6
V = 162 cm^3
