Dear Student,
Radius of circle = 3
5 cm So circumference = 2πr=2×227×3
5= 22 cm Now quadrater of circle makes and angle 90 degree at the center so So perimeter of quarter of circle= 90360× 2πr+2r=14×22+7= 5
5+7= 12
5 cmNow you answer is coming 5
5 because you forgot to add two sides that are radiusyou can visulaize by seeing the quarter of circle
