    r = 14.998 yd

    Step-by-step explanation:

    Volume of a cone

    V = πr^2h/3

    Given:

    V = 3,532 yd cubed

    π - 3.14

    r = h

    Since the radius and the height of the cone are equal

    So, let r = h = x yd

    V = 3.14 * x^2 * x/3

    3532 = 3.14x^3/3

    3532 = 1.047x^3

    Divide both sides by 1.047

    3532/1.047 = x^3

    3373.45 = x^3

    x = 14.998 yd

    Since r = h = x

    r = h = 14.998yd

    r = 14.998yd

    Hint: to check if the value of radius and the height are correct, insert the values into the formula

    V = πr^2h/3

    V = 3.14 * 14.998^2 * 14.998/3

    = 3.14 * 224.940 * 4.999

    = 3530.852

    ≈ 3531 yd cubed
