Jawaban:

Lp = 452,16 cm²

V = 401,92 cm³

Penjelasan dengan langkah-langkah:

r = 8cm

t = 6cm

s = √(8²+6² = √(64+36) = √100 = 10cm

Lp kerucut = π r (r + s) = 3,14. 8 (8 + 10) = 3,14. 8 (18)

= 3,14. 144 = 452,16 cm²

V kerucut = ⅓ π r² t = ⅓. 3,14. 8². 6 = ⅓. 3,14. 64. 6

= ⅓. 3,14. 384 = 128. 3,14 = 401,92 cm³
