Write a function to model the area of a round plate. Evaluate the function for a plate of radius 5.5 in.

Area of circle = pi*radius²

$${\mathtt{Area}} = {\mathtt{\pi}}{\mathtt{\,\times\,}}{{\mathtt{5.5}}}^{{\mathtt{2}}} \Rightarrow {\mathtt{Area}} = {\mathtt{95.033\: \!177\: \!771\: \!091\: \!245\: \!5}}$$

Area of plate ≈ 95 in²
