Question

The oven tray is 600mm by 500mm. A cake tin is 25cm in diameter. How many cake tins can jenny fit on the oven tray at one time?

Answer 1

Area of Oven Tray = 60 * 50 = 3000

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

Number of Cake Tins that will fit =
`(Total-space-on-oven-tray-available)/(Area-occupied-by-single-cake-tin)`
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.
