Answer:
2855.0
Step-by-step explanation:
there are several surface areas.
1. outside surface of the cylinder = circle circumference times height = 2*pi*r*height = 2*pi*14*14 = 1231.5
2. top and bottom of the cylinder = circle area times 2 = pi*r^2 * 2 = pi*14^2 *2 = also 1231.5
3. subtract the 2 cut out rectangles on the top and the bottom = 2* 6*14 = 168
4. add the areas of the inside walls of the cut out block.
there are 2 narrow rectangles = 2* 6*14 = 168
there are 2 squares = 2* 14*14 = 392
so, 1.+2.-3.+4. = 2855.0 (2855.00864...)
First let's calculate how much oil the cook uses per week.
15(2 kg) = 30 kg per 4 weeks
This means the cook averages 30 kg per 4 weeks →

or 7.5 kg per week
Next let's calculate how much oil the cook will need for 10 weeks.
7.5 kg/weeks × (10 weeks) = 75 kg ← the weeks units cancel out
Finally divide the amount of oil the cook needs for 10 weeks by the amount of oil in a 5 kg tin.
75 ÷ 5 = 15
ANSWER: The cook will need
fifteen 5 kg tins of oil.
A prime number can only be divided by one oritslef and a composite number can bedivided by other njmbers.
