Answer by Rupesh..

Outer Circumference = 132 cm

Outer Circumference = 132 cm=> Radius = Circumference / 2π

Outer Circumference = 132 cm=> Radius = Circumference / 2π=> Radius = 132 / (2 × 22/7)

Outer Circumference = 132 cm=> Radius = Circumference / 2π=> Radius = 132 / (2 × 22/7)=> Radius = 132 / (44/7)

Outer Circumference = 132 cm=> Radius = Circumference / 2π=> Radius = 132 / (2 × 22/7)=> Radius = 132 / (44/7)=> Radius = 132 × 7/44

Outer Circumference = 132 cm=> Radius = Circumference / 2π=> Radius = 132 / (2 × 22/7)=> Radius = 132 / (44/7)=> Radius = 132 × 7/44=> Radius = 3 × 7

Outer Circumference = 132 cm=> Radius = Circumference / 2π=> Radius = 132 / (2 × 22/7)=> Radius = 132 / (44/7)=> Radius = 132 × 7/44=> Radius = 3 × 7=> Radius = 21 cm

Outer Circumference = 132 cm=> Radius = Circumference / 2π=> Radius = 132 / (2 × 22/7)=> Radius = 132 / (44/7)=> Radius = 132 × 7/44=> Radius = 3 × 7=> Radius = 21 cmInner Circumference = 88 cm
