since the principal axis goes through the center of circle so line perpendicular to the principal axis from center of circle to the circumference of circle will form a line equal to half the height of object i.e 20cm(it is half because whple circle is 20+20 cm) so now we have ho=20 cm u= -30cm ( as mirror is 30cm away from center of circle) and f= -20cm by mirror formula :- 1/v+1/u=1/f =>1/v-1/30= -1/20 => 1/v= 1/30 - 1/20 => 1/v = 2-3/60 => v = - 60 cm now by magnification in mirror:- -v/u = hi/ho = m => -(-60)/(-30) = hi/20 =>-2 (20) = hi => hi = -40 cm so now the radius of crcle formed by image is equal to hi i.e radius of circle formed is 40cm

Teamwork is working in a group of two and more people to achieve a common goal. Teamwork builds your identity and gives you purpose. It helps you set clear goals and work towards them in a group. The problem with working alone is you can get easily derailed or demotivated.
