Penjelasan dengan langkah-langkah:
v = 16.632 cm³
t = 36 cm
v = 1/3 x π x r² x t
16.632 = 1/3 x 22/7 x r² x 36
16.632 x 7 = 12 x 22 x r²
116.424 = 264 x r²
r² = 116.424 : 264
r² = 441
r = √441
r = 21 cm
jari jari alas kerucut
V = ⅓ × πr²t
16.632 = ⅓ × 22/7 × r² × 36
r = √(16.632 ÷ (⅓ × 22/7 × 36))
r = √(16.632 ÷ (⅓ × 792/7))
r = √(16.632 ÷ (264/7))
r = √(16.632 ÷ 264/7)
r = √(16.632 × 7/264)
r = √(116.424/264)
