  • area=πr^2

    so we need to find the area then divide by 8

    so
    we know that diameter=2radius or diameter/2=radius so
    12=diameter
    12/2=radius=6
    subsitute
    area=π(6)^2
    area=36π
    divide 36π by 8
    36π/8=18π/4=9π/2π=4.5π
    area of one section is 4.5π square feet or if we aprox pito 3.14159 then we get
    4.5(3.14159)=area=14.1372 square feet or 14.14 square feet
