Mohammed has a garden in the shape of a semi-circle. If the width of the garden, at it’s widest point, is 14 feet, how large is the garden in square yards. Thank you in advance.

  • math - ,

    The radius is 7 feet = 2.33 yards

    Circle Area = pi * r^2
    A = 3.14 * 2.33 * 2.33
    A = 17.0467

    Half of that is 8.52 square yards.

  • math - ,

    The widest point=14ft.=4.7yds.=diameter
    A=(pi)r^2/2=3.14(2.35)^2/2=8.67 sq yds.

  • math - ,

    Our difference comes in how we rounded.
