\begin{gathered} \text{Circunference = pi}\cdot(d^2)/(4) \\ \text{Circunference = (3.14)}\cdot\text{ }(21^2)/(4) \\ \text{Circunference = (3.14) }\cdot\text{ }(441)/(4) \\ \text{Circunference = (3.14) }\cdot\text{ 110.25} \\ \text{Circunference = 346.19 in}^2 \end{gathered}

The result is 346.19 in^2
