Best ResponseYou've already chosen the best response.0Well, you can calculate the area of a circle with the following formula: \[A _{\circ}= \pi r^2\] So, therefore: \[A_ \circ = \pi (6)^2\]

Best ResponseYou've already chosen the best response.2the requested area is given by this formula: \[A = \pi \times \frac{{{D^2}}}{4} = \pi \times \frac{{36}}{4} = ...inche{s^2}\]
