Draw concentric circle for the following measurements of radii/diameters. Find out the width of the circular ring.
r = 3.5 cm and r = 6.5 cm
उत्तर
r = 3.5 cm and r = 6.5 cm
Step 1: Drawn a rough diagram and market the given measurements
Step 2: Taken any point O and marked it as the center.
Step 3: With O as center drawn a circle of radius OA = 3.5 cm.
Step 4: With O as center drawn a circle of radius OB = 6.5 cm.
Thus the concentric circles C1 and C2 are drawn.
Width of the circular ring = OB – OA = 6.5 – 3.5 = 3 cm
