    Answer:

    90.5 cups

    Step-by-step explanation:

    Step one:

    Given data

    diameter= 24ft

    radius= 12 ft

    area= πr^2

    Area= 3.142*12^2

    Area= 3.142*144

    Area= 452.448 ft^2

    Hence if  

    2 cups of fertilizer for every 10 square feet

    x cups will do for  452.448 ft^2

    cross multiply we have

    x=  452.448 *2/10

    x=904.896/10

    x=90.5 cups

    ANSWER:

    Area of circular garden = πr²

    • 3.14 × (12)²
    • 3.14 × 144
    • 452.16ft²

    So, For 10ft² = 2cups

    Therefore, 452.16ft² = 452.16/5

    • 90.432 or 90 cups approx.
