Here are the dimensions of the oven tray lucy bakes the cakes on. ←700mm→↑600mm↓.a cake tin is 25cm in diameter. how many cake tins can lucy fit on the oven tray at one time?

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

Hence, exactly 8 cakes fit on the oven tray at one time.

17,000 is the correct answer.
