Question 189686
a) calculate the diameter of the circle



C=2*pi*r


14.5=2*3.14*r


14.5/(2*3.14)=r


14.5/(6.28)=r


2.31=r


r=2.31


diameter: d=2*r=2(2.31)=4.62


-------------------


b) from part a) radius: r=2.31


-------------------

c)

Area:

A=pi*r^2


A=(3.14)(2.31)^2


A=(3.14)(5.3361)


A=16.755
