Answer:
8
Step-by-step explanation:
Dimension of the oven = 700 mm × 600 mm
First we change mm to cm
As we know 10 mm = 1 cm
So, 700 mm = 70 cm and 600 mm = 60 cm
Area of base of the oven = 60 × 70
= 4200 cm²
A cake whose base is circular in 25 cm diameter.
Radius is half of diameter, r=12.5 cm
So, Area of the base of tin cake = πr²
= π×12.5²
≈ 490.87 cm²
Number of cake fit on the oven tray [tex]=\dfrac{\text{Area of oven}}{\text{Base area of cake}}[/tex]
[tex]=\dfrac{4200}{490.87}[/tex]
[tex]\approx 8.55[/tex]
Hence, exactly 8 cakes fit on the oven tray at one time.
