Hitunglah luas permukaan bangun berikut.
Jawaban:
Gambar 1
L = 22 x (r x r)
L = 22 x (9 x 9)
L = 22 x 81
L = 1.782 cm2
Gambar 2
L = 18 x (r x r)
L = 18 x (7 x 7)
L = 18 x 49
L = 882 cm2
Gambar 3
L = 10 x (r x r)
L = 10 x (10 x 10)
L = 10 x 100
L = 1.000 cm2
Gambar 4
L = 14 x (r x r)
L = 14 x (12 x 12)
L = 14 x 144
L = 2.016 cm2
Gambar 5
L = 28 x (r x r)
L = 28 x (10 x 10)
L = 28 x 100
L = 2.800 cm2
Gambar 6
L = 5 x (10 x 10) + 5 x (6 x 6) + (10 x 10) – (6 x 6)
L = 5 x 100 + 5 x 36 + 100 - 36
L = 500 + 180 + 64
L = 744 cm2
