Luas P1
=(150/360)×3.142×30² - (150/360)×3.142×5²
=1145.52cm²

luas P2
=2/3×P1
=2/3×1145.52
=763.68cm²

jumlah luas
=luas P1+luas P2
=1145.52+763.68
=1909.20cm²

oopppss..kena guna 1/2j²theta..jap betulkan balik..
luas P1
=1/2(150/180)×3.142×30² - 1/2(150/180)×3.142×5²
=1145.52cm²
nape kena darab ngan 150/180 bukan 360
dah guna 1/2 kat depan tu...klu guna rumus theta..
tk faham
