Answer» ,CIRCUMFERENCE of CIRCLE = 2πrWhere,R is radius of circle.π is 22/7 or 3.14. a. A circle with radius 63 cm.r = 63 cmPut r in circumference formula 2 × 22/7 × 63 44/7 × 63 2772/7 396Therefore,Circumference of circle is 396 cm.b. A circle with DIAMETER 8.4 m.r = Diameter/2= 8.4/2= 4.2Radius (or r) of circle is 4.2 mNow, PUT r in circumference formula : 2 × 22/7 × 4.2 44/7 × 4.2 184.8/7 26.4Therefore,Circumference of circle is 26.4 m. |
