X = cups of tea per hour
y = cups of coffee per hour
David makes 30 cups of tea per hour = 30x
David works for D hours this week.
Therefore number of weekly cups of tea = number of hours * cups of tea per hour
This is 30x * D = 30Dx
For Andrew, it is similar
30Ay
Because Andrew made an additional 10 cups, then it is 30Ay + 10
(cups of coffee this week)

Answer:
- 36π in^2
- 460π ft^2
- 216π yd^2
Step-by-step explanation:
The formula for total surface area of a cylinder is ...
total area = total base area + lateral area
= 2(base area) + lateral area
= 2(πr^2) +2πrh
= 2πr(r +h)
This formula has been put into the attached spreadsheet so it can do the arithmetic. You will notice that we left out the factor of pi, because we want to use the symbol to represent its exact value. Note, too, that the radius is half the diameter.
The areas are ...
1) 36π square inches
2) 460π square feet
3) 216π square yards
