Okay, here we have this:

Considering the provided information we are going to calculate the circumference and the area of the circle, so we obtain the following:

Circumference:


\begin{gathered} C=\pi d \\ C=\pi(14cm) \\ C=14\pi cm \\ C\approx43.98\operatorname{cm} \end{gathered}

Area:


\begin{gathered} A=\pi r^2 \\ A=\pi((14)/(2)cm)^2 \\ A=\pi(7cm)^2 \\ A=49\pi cm^2 \\ A\approx153.94cm^2 \end{gathered}
