Question

Draw concentric circle for the following measurements of radii/diameters. Find out the width of the circular ring.

r = 3 cm and r = 5 cm

Answer 1

r = 3 cm and r = 5 cm

Width of the circular ring = OB – OA = 5 – 3 = 2 cm

Step 1: Drawn a rough diagram and market the given measurements

Step2: Taken any point O and marked it as center.

Step 3: With O as center drawn a circle of radius OA = 3 cm.

Step 4: With O as center drawn a circle of radius OB = 5 cm.

Thus concentric circles C₁ and C₂ are drawn.

Width of the circular ring = OB – OA = 5 – 3 = 2 cm
