Jawaban:

C.

Penjelasan dengan langkah-langkah:

diameter 12 dm

radius (jari-jari) = 12/2 = 6 dm

..

LP kerucut

= πr(r + s)

..

376,8 = 3,14 × 6(6 + s)

376,8 = 18,84(6 + s)

376,8 = 113,04 + 18,84s

18,84s = 376,8 - 113,04

18,84s = 263,76

s = 263,76/18,84

s = 14 cm

Answer 2

garis pelukis

LP = πr(r + s)

LP = 3,14 × (12 ÷ 2) × (r + s)

LP = 3,14 × 6 × (6 + s)

376,8 = 3,14 × 6 × (6 + s)

376,8 = 18,84 × (6 + s)

376,8 = (18,84 × 6) + (18,84 × s)

376,8 = 113,04 + 18,84s

18,84s = 376,8 - 113,04

18,84s = 263,76

s = 263,76/18,84

s = 14 dm
