Answer:
530.66 cm²
Step-by-step explanation:
A formula for the area of the circular disc can be written as ...
A = C²/(4π)
A = (81.64²)/(4·3.14) = 6665.0896/12.56
A = 530.66 . . . . square centimeters
Write the equation out: (total cost: 0.35C[per carton] + 75[delivery charge]) ≤ 500. Subtract 75 on both sides and it would be: 0.35C ≤ 425. Divide 0.35 on both sides and you'll get C ≤ 1214. Therefore, the maximum # of cartons that Elvira can buy is 1214 cartons of milk.
