Bantu pakek caranya kak

L alas + L selimut + L 1/2 bola

=(π×r²)+((π×d)×t)+((4×π×r²)×1/2)

=(22/7×7²)+((22/7×14)×10)+((4×22/7×7²)×1/2)

=154+440+308

= 902cm²

d = 14 cm

r = d/2 = 14/2 = 7 cm

Luas Permukaan

= Tabung tanpa tutup + ½ bola

= (π × r × (r + 2 × t)) + (½ × 4 × π × r²)

= (22/7 × 7 × (7 + 2 × 10)) + (½ × 4 × 22/7 × 7 × 7)

= (22/7 × 7 × (7 + 20) + (2 × 22/7 × 7 × 7)

= (22/7 × 7 × 27) + (2 × 22 × 7)

= (22 × 27) + 308

= 594 + 308

= 902 cm²
