white=4^2 π−3^2 π+2^2 π=(16+4−9)π=11π  blue=6^2 π−white=(36−11)π=25π
$${white}=\mathrm{4}^{\mathrm{2}} \pi−\mathrm{3}^{\mathrm{2}} \pi+\mathrm{2}^{\mathrm{2}} \pi=\left(\mathrm{16}+\mathrm{4}−\mathrm{9}\right)\pi=\mathrm{11}\pi \\ $$$${blue}=\mathrm{6}^{\mathrm{2}} \pi−{white}=\left(\mathrm{36}−\mathrm{11}\right)\pi=\mathrm{25}\pi \\ $$
