Part one particular

Geometry вЂ“ To determine suited dimensions for the cake, to assist in designing and decorating bread that comes in many eye-catching shapes and designs, to calculate volume of pastry to be developed.

Calculus ( Differentiation ) вЂ“ To determine minimum or maximum quantity of elements for dessert вЂ“ baking, to estimation minimum or maximum, quantity of cream needed for decorating, to estimation minimum or maximum size of cake produced.

Progressions вЂ“ To determine total weight / volume of multi-storey cakes with proportional proportions, to calculate total substances needed for cake-baking, to calculate total quantity of cream for decor.

Part a couple of

1) Given 1 kg of cake has amount 3800 cmВі, and l is several cm, so find the d. Amount of 5 kilogram = Bottom area of cake x Level of wedding cake 3800 times 5 = (3. 142) (d/2)ВІ back button 7

19000 / 7 (3. 142) = (d/2)ВІ

863. 872 = (d/2)ВІ

d/2 = 29. 392

d = 58. 784

2) Presented the inner proportions of the oven: 80 centimeter length, 70 cm width, 45 cm height

a) Locate corresponding principles of d with different values of h, and tabulate the answers. First, constitute the formula intended for d regarding h by using the above formulation for amount of cake, Versus = 19000, that is: 19000 = (3. 142)(d/2)ВІh

19000/(3. 142)h sama dengan dВІ/4

24188. 415/h = dВІ

g = one hundred fifty five. 53/в€љh

|Height, they would (cm) |Diameter, d (cm) | |1. 0 |155. 53 | |2. zero |109. 98 | |3. 0 |89. 80 | |4. 0 |77. 77 | |5. 0 |69. 56 | |6. 0 |63. 49 | |7. 0 |58. 78 | |8. zero |54. 99 | |9. 0 |51. 84 | |10. zero |49. 18

b) i) h < 7 cm is certainly not suitable, for the reason that resulting size produced is actually large to match into the oven. Furthermore, the cake would be too short and too extensive, making it fewer attractive.

ii) h sama dengan 8 cm, d = 54. 99 cm, as it can match he range, and the size is suitable for easy handling.

c) i) The same method in Q2(a) is used, that may be 19000 = (3. 142)(d/2)ВІh. The same process ia as well used, that may be make m as this issue. This time, form an formula which is ideal and relevant for the graph:

19000 = (3. 142)(d/2)ВІh

19000/(3. 142)h sama dengan dВІ/4

24188. 415/h = dВІ

m = 155. 53/в€љh

d = one hundred fifty five. 53hЛ‰В№ ВІ

log g = journal 155. 53hЛ‰В№ ВІ

journal d sama dengan -1/2 sign h & log one hundred fifty five. 53 (the final equation for chart вЂ“ drawing)

|Height, h (cm) |Diameter, g (cm) |Log h |Log d | |1. zero |155. 53 |0. 500 |2. 192 | |2. 0 |109. 98 |0. 300 |2. 041 | |3. 0 |89. eighty |0. 477 |1. 953 | |4. 0 |77. 77 |0. 602...
