No 24 sama 25 pakai cara ya !

24. Persegi panjang + Trapesium - Lingkaran

L persegei panjang = pxl = 30cm x 16 cm = 480 cm²
L trapesium = (a+b)t/2 = (30+20).14/2 = 350 cm²
L lingkaran = π/4D² = (22/7)/4 . (14)² = 154 cm²
Ltotal = (480+350-154)=676 cm²

25. Vtabung = πr²t

r =14/2 = 7cm
t= 25 cm
V = πr²t = 22/7.(7)².(25) = 3850 cm³
