DO YOU REALLY NEED SOMEONE TO do a calculation of Circumference = pi * D or 2*pi*R ? Surely you jest!!

(1) AA pentagon has 5 sides. 60/5 = 12"(2) CCirc = D*pi = 30*3.14159 = 94.248(3) DCirc = 2*pi*r ==>42 = 2*3.14159*rr = 6.6845(4) ACirc = pi*D ==>9.42 = 3.14*DD = 3

1) A 12 in. 60/5 sides = 122) C=d*pi=30*3.14=94.2 cm3) C=2pi*r...42=2pi*r....42/(2pi) = 6.69 in.4) C=pi*d...9.42=pi*d....9.42/pi = 3 cm

60/5=12, so A is correct.30/2*2pi=9434, so C is correct.42/2pi=6.69, so D is correct.9.42/2pi=3, so A is correct.
