A. 292,02 cm²
Penjelasan dengan langkah-langkah:
d = 6 cm
r = 3 cm
s² = 4² + 3²
= 16 + 9 = 25
s = √25 = 5. m
L1 = L 1/2 bola
= 1/2 x 4 x πr²
= 2 x 3,14 x 3 x 3
= 56,52 cm²
L2 = L selimut tabung
= πdt
= 3,14 x 6 x 10
= 188,4 cm²
L3 = L selimut kerucut
= πrs
= 3,14 x 3 x 5
= 47,1 cm²
L gabungan adalah
= 56,52 + 188,4 + 47,1
= 292,02 cm²
