Jawaban:
1. Volume kerucut = 1/3 x phi x raxt = 1/3 x 22/7 x 212 x 30
= 1/3 x 22/7 x 441 x 30
= 1/3 x 1.386 x 30
= 462 x 30
= 13.860cm3
2. Volume limas segiempat = 1/3 x panjang x
lebar x tinggi
= 1/3 x 18 x 15 x 20
= 1/3 x 270 x 20 = 1/3 x 5.400
= 1.800cm3
Penjelasan dengan langkah-langkah:
semoga membantu
Jawab:
Dik= r= 21cm
T=30 cm
Dit =volume kerucut?
Jawab= v=1/3×phi ×r×r
V=1/3×3,14×21 cm ×21cm
V=461,58
Jadi, volume kerucut nya 461,48
