Pls ya kakak
Jawab:
1. V= (1/2 x alas segitiga x tinggi segitiga) x tinggi prisma
= (1/2 x 7 x 9) x 8
= 31,5 x 8
= 252 cm^3.
2. V= (1/2 x alas segitiga x tinggi segitiga) x tinggi prisma
= (1/2 x 13 x 100) x 16
= 650 x 16
= 10.400 cm^3.
3. V= (1/2 x alas segitiga x tinggi segitiga) x tinggi prisma
= (1/2 x 23 x 14) x 20
= 161 x 20
= 3.220 cm^3.
4. V= (1/2 x alas segitiga x tinggi segitiga) x tinggi prisma
= (1/2 x 7 x 6) x 13
= 21 x 13
= 273 dm^3.
5. V= (1/2 x alas segitiga x tinggi segitiga) x tinggi prisma
= (1/2 x 23 x 32) x 28
= 368 x 28
= 10.304 m^3.
6. V= phi x r x r x t
= 22/7 x 7 x 7 x 16
= 2464 cm^3.
7. V= phi x r x r x t
= 22/7 x 14 x 14 x 25
= 15.400 cm^3.
8. V= phi x r x r x t
= 22/7 x 7 x 7 x 11
= 1694 cm^3.
9. V= phi x r x r x t
= 22/7 x 14 x 14 x 23
= 14.168 m^3.
10. V= phi x r x r x t
= 22/7 x 35 x 35 x 80
= 308.000 cm^3.
Semoga Membantu! ^o^
