jawaban:
4082cm^2
Penjelasan dengan langkah-langkah:
L permukaan bangun = Lp Kerucut + Lp 1/2 bola
Lp kerucut (tanpa alas) = π × r × s
s = √(t kerucut)^2 + (r bola)^2
t ker = t bangun - r bola = 35 - 20 = 15cm
s = √15^2 + 20^2
s = √225 + 400
S = √625
s = 25cm
Lp kerucut (tanpa alas) = 3,14 × 20 × 25 = 1570cm^2
Lp 1/2 Bola = 2πr^2
Lp 1/2 Bola = 2 × 3,14 × 20 × 20
= 2512cm^2
Lp bangun = 1570 + 2512 = 4082cm^2
Maaf kalo salah
Semoga membantu temann
