1. diameter kerucut 10 cm
apotema kerucut 20 cm
berapa luas permukaan kerucut?

2.sebuah kerucut jari jarinya 14 cm dan tinggi kerucut 24 cm berapa volume kerucut?​

Luas permukaan kerucut = 942 cm

Volume kerucut = 4,928 cm

Penjelasan dengan langkah-langkah:

Lp kerucut = π × d × d + π × d × a

= 3,14 × 10 × 10 + 3,14 × 10 × 20

= 314 + 628

= 942 cm

V kerucut = ⅓ × π × r × r × t

= ⅓ × 22/7 × 14 × 14 × 24

= ⅓ × 22 × 2 × 14 × 24

= ⅓ × 14,784

= 4,928 cm
