Step-by-step explanation:
soo here is the answer
170 degree is the value of =x
and the value of uly is 110 degree
Oven tray: 600 mm by 500 mm
cake tin: 25 cm in diameter
convert mm to cm.
1 cm = 10 mm
600mm * 1cm/10mm = 60cm
500mm * 1cm/10mm = 50cm
Area of oven tray = 60cm * 50cm = 3,000 cm²
Area of cake tin = 3.14 * (25cm/2)² = 3.14 * (12.5cm)² = 3.14 * 156.25cm² = 490.625 cm²
3,000cm² ÷ 490.625cm² = 6.11 or 6 cake tins can fit on the oven tray at one time.
