So we wan't to calculate the radius of a sphere that has the area of Alaska that is A=663.267 square miles. First, lets see what is the formula for the area of the sphere: A= 4*pi*r^2. Here we can solve the equation to get the radius: r^2=A/(4*pi) and the last step is: r= sqrt ( A/(4*pi) ). After we input the numbers we get: r= 224.54 miles.
