A circular garden has a circumference of 88 yards. Lars is digging a straight line along a diameter of the garden at a rate of 7 yards per hour. How many hours will it take him to dig across the garden? Use 3.14 for π and round the diameter to the nearest whole number, if necessary.

    It will take 4 hours to dig in the garden

    Step-by-step explanation:

    First we have to calculate the diameter, for this we will use the formula to calculate the circumference of a circle and we will clear the diameter

    d = diameter

    π = 3.14

    c = circumference

    c = π * d

    d = c / π

    d = 88yd / 3.14

    d = 28.025yd

    round to the nearest whole number

    28.025 = 28

    d = 28yd

    To know how many hours it takes, we divide the diameter by the speed

    t = time

    v = velocity

    t = d / v

    t = (28yd) / (7yd/h)

    t = 4h

    It will take 4 hours to dig in the garden
