Penjelasan dengan langkah-langkah:
a) Volume = 1/3 x Phi x r^2 x t
12p+10 = 1/3 × 22/7 × (3,5)^2 × p
12p+10 = 1/3 × 22/7 × 12,25 × p
12p+10 = 12,833p
12p-12,833p = -10
0,833p = -10
p = 12,0048 = 12
jadi, tinggi kerucut = 12 cm
b) Volume = 12p+10 = 12(12)+10 = 154 cm^3
c) mencari garis pelukis kerucut (s)
luas sisi = luas alas + luas selimut
= Phi×r^2 + Phi×r×s
= 22/7×(3,5)^2 + 22/7×3,5×12,5
= 38,5 + 137,5
= 176 cm^2
