Question

tolong dong yg ngasal laporin​

Answer 1

Jawaban:

a. Jari - jari : 12÷2 = 6 cm

Tinggi : t = √100-36 = √64 = 8 cm

Luas : L = 3,14 × 6 ( 6 + 10 ) = 18,84 × 16 = 301,44 cm²

Volume : V = 1/3 × 3,14 × 36 × 8 = 904,32/3 = 301,44 cm³

b. Diameter : 10×2 = 20 cm

Tinggi : t = √676-100 = √576 = 24 cm

Luas : L = 3,14 × 10 ( 10 + 26 ) = 31,4 × 36 = 1130,4 cm²

Volume : V = 1/3 × 3,14 × 100 × 24 = 7536/3 = 2512 cm³

semoga membantu :)
