First you need to find the area of the baking tray.
500 x 700 = 350,000 mm^2
Next, you must find the area of the "circles" or "cakes".
3.14r^2
3.14(25^2)
3.14(625)
1962.5 mm^2
Finally, you will have to divide the area of the baking tray by the area of the circle/cake.
350,000/1962.5
178.34 cakes
So, your final answer will be....
Approx 178 circles/cakes can fit in the oven.
Hope this helps!
