A:
Answer:The perimeter of a circle can be found by using the followinfg expressionP = 2*π*rwhereπ = 3.14r  = radius of the circle = half the diameter of the circleIn this case, if we are given the radius, we useP = 2*π*rIf we are given the diameter, we useP = 2*π*(D/2) = π*D1) 27inradius = 27inP = 2*(3.14)*(27 in) = 169.56 indiameter = 27 inP = (3.14)*(27 in) = 84.78 in2) 79 inradius = 79 inP = 2*(3.14)*(79 in) = 496.12 indiameter = 79 inP = (3.14)*(79 in) = 248.06 in3) 1809 inradius = 1809 inP = 2*(3.14)*(1809 in) = 11360.52 indiameter = 1809 inP = (3.14)*(1809 in) = 5680.26 in4) 152 inradius = 152 inP = 2*(3.14)*(152 in) = 954.56 indiameter = 152 inP = (3.14)*(152 in) = 477.28 in
