Answer» We KNOW,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\longrightarrow⟶ 2 × 22/7 × 63\longrightarrow⟶ 44/7 × 63\longrightarrow⟶ 2772/7\longrightarrow⟶ 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 :\longrightarrow⟶ 2 × 22/7 × 4.2\longrightarrow⟶ 44/7 × 4.2\longrightarrow⟶ 184.8/7\longrightarrow⟶ 26.4Therefore,Circumference of circle is 26.4 m.
