kak tolong ya yang no (1 bgian A) dan no (2)​

Jawaban:

1.A = 51,3

2. = 66

Penjelasan dengan langkah-langkah:

VK = 1/3×π×r²

=1/3×22/7×7×7

=7:7

= 1

= 22×1×7

= 154:3

=51,3

VK = 1/3×π×r²

= 1/3×22/7×21×30

= 21:7

= 3

= 22×3×30

= 1/3:198

= 66

MAAF KALAU SALAH!!

1. L.Alas = 22/7 x 7 x 7 = 154 cm2
Volume = L.Alas x tinggi = 154 x 20 = 3080 cm3

2. L.Alas = 22/7 x 21 x 21 = 1386 cm2
Volume = L.Alas x tinggi = 1386 x 30 = 41580 cm3
