Area of Oven Tray = 60 * 50 = 3000

Area of Cake Tin = [tex] \pi [/tex]r²
r = 25/2 = 12.5
Area of Cake Tin = [tex] \pi [/tex](12.5)²
= 156.25[tex] \pi [/tex] = 490.87....

Number of Cake Tins that will fit =[tex] \frac{Total-space-on-oven-tray-available}{Area-occupied-by-single-cake-tin} [/tex]
Number of Cake Tins that will fit = 3000/490.87.... = 6.1115....
You can't have 0.11154.... of a tray so the answer is just 6.
