tester [92]

Answer:

For the 1st question (4) For the 2nd question (1)

Step-by-step explanation:

(4) because 15000x+10000y needs to be less than or equal to 20000 or else they're going over the budget but x+y needs to be less than or equal to 15 as they can't make more than that.

(1) Divide both sides by pi and h then square root both sides.
