jawaban nomer 8
luas = ( s x s ) – ( π x r² )
= ( 14 x 14) – ( 22/7 x 7 x 7)
= 196 – 154
= 42 cm²
jawaban nomer 9
d = 14 cm
kliling = d + ( π x d)
= 14 + ( 22/7 x 14)
= 14 + 44
= 58 cm
jawaban nomer 10
s = r = 10 cm
luas = ( s x s ) + ( 3/4 x π x r²)
= ( 10 x 10) + ( 3/4 x 3,14 x 10 x 10)
= 100 + ( 3/4 x 314)
= 100 + 235,5
= 335,5 cm²
