Jawaban:

soal:

hitung volume dan luas permukaan dari bangun disamping jika r=5 cm

jawaban+cara:

-siring

=✓12²+5² =✓144+25 =✓169 =13 cm

1)Volume gabungan

=Vtabung + Vkerucut

=π×r×r×t + 1/3×π×r×r×t

=3,14×5×5×24 + 1/3×3,14×5×5×12

=1.884 + 3,14×5×5×4

=1.884 + 314

=2.198 cm³

2)Luas gabungan

=Ltabung tanpa tutup + Lkerucut

=π×r×(r+2t) + π×r×(r+s)

=3,14×5×(5+2×24) + 3,14×5×(5+13)

=15,7×(5+48) + 15,7×18

=15,7×53 + 282,6

=813,1 + 282,6

=1.114,7 cm²
