Answer:
He must charge minimum £0.84 for one hot dog.
Step-by-step explanation:
Ingredients cost for hot dogs at the supermarket,
Price of dog sausages tin of 8 = 50p ≈ £0.5
Price of dog bun packs of 6 = 90p ≈ £0.90
Number of tins required for 150 hot dogs = 
= 6.25
So student will purchase 7 tins.
Cost of 7 tins = 7 × 0.5
= £3.5
Number of dog buns packets required = 
= 25
Cost of 25 packs = 25 × 0.9
= £22.5
Total cost of the material used for 150 buns = 22.5 + 3.5
= £26.0
Let the selling price of each hot dog = £x
Then selling price of 150 hot dogs = £150x
Students wants the profit = £100
So, Selling price - Cost price = profit
150x - 26 = 100
150x = 126
x = 
x = £0.84
Therefore, he must charge minimum £0.84 for one hot dog.

Answer:
The height of cylinder is: h = 80.07 cm
The diameter of cylinder is: d = 3.5 cm
Step-by-step explanation:
Curved surface area of cylinder = 880 cm^2
Volume of cylinder = 770 cm^3
We need to find its diameter and height.
The formula used are:
If we divide volume by curved surface, we can find radius
So, we get radius r = 1.75
Now, we can find height using curve surface area formula:
So, the height of cylinder is: h=80.07 cm
Now finding diameter using formula: 
Putting value of r in above formula:
So, the diameter of cylinder is: d = 3.5 cm
Answer: C= Pi times diameter
