Answer:
452.45mmm^2
Step-by-step explanation:
Step one:
Given data
outer radius R= 20mm
inner radius r= 16mm
let us find the area of the outer circle
Area= πR^2
Area= 3.142*20^2
Area= 3.142*400
Area= 1256.8 mm^2
let us find the area of the inner circle
Area= πr^2
Area= 3.142*16^2
Area= 3.142*256
Area= 804.35 mm^2
Hence the area of the section is
Area of outer- Area of inner
=1256.8-804.35
=452.45mmm^2
