Penjelasan dengan langkah-langkah:
r = 14 /2 = 7 cm
t tabung = 12 cm
t kerucut = 36-12 = 24 cm
s² = r² + t²
s = √(7x7) + (24x24)
= √(49+576)
= √526 = 25 cm
I Luas tabung
Luas Alas + (Keliling alas x tinggi)
(π x r²) + (π D x t)
(22/7 x 7 x 7) + (22/7 x 14 x 12)
154 + 528
682 cm
Luas Kerucut
π x r x s
22/7 x 7 x 25
550 cm
Luas total
682 + 550 = 1.232 cm²
