The area of a round plate is a function of the radius of the circle. 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
