Best ResponseYou've already chosen the best response.1Then the formula for a circumference of a circle is \[\pi*d=\pi*2=2\pi\] where d = diameter, and that's just pi

Best ResponseYou've already chosen the best response.1Yes there is: The formula for area is \[2\pi*r^2\] where r = radius Now you need to know that diameter = 2*radius So d = 2r Since d = 2 2 = 2r r = 1 So the area is \[2\pi*r^2=2\pi(1)^2=2\pi \] in inches^2 as units
