From the information given, the tins are circular /cylindrical because they have a diameter.
So we need to find out the base area of each tin .
Base Area = π r²
radius here will be 25/2 = 12.5
Area = 3.14 × 12.5 ×12.5
Area = 490.6cm²
For the tray the dimensions are 600mm and 500mm which seem to allude the trays are of a regular shape such as a rectangle. Let us assume it is so.
600mm = 60cm, and 500mm = 50cm
Area = L × w
Area = 50 × 60 = 3000cm²
Each tray will fit 3000 ÷ 490.6 = 6.1
6 cake tins will fit into one tray
Answer:
6y^2√10 +12y √5
Step-by-step explanation:
3√10(y^2√4 + √8y)
Distribute
3√10(y^2√4) +3√10 (√8y)
3y^2 √40+3y√80
We know that √ab = √a√b
3y^2 √4*√10+3y√16√5
3y^2 *2*√10+3y*4√5
6y^2√10 +12y √5
Measure which ever side of the triangle and that’ll be the length of pq
12-13= yx this is that expression
Ok well since it said “how much more we subtract 11-7=4
