$\huge\mathfrak\red{Question :) }$

What is the cross sectional area of a circular ring of D=38mm,d=32mm

$\huge\mathfrak\red{Answer :) }$

Formula to solve this is

$\tt { \fbox {\pink {Pie=R1*R2}}}$

Here r1=38 and R2=32

So,,, putting value

$3.14( {38}^{2} - {32}^{2} )$

$1318.8$

Hence the answer id 1318.8
