Answer:
if a wire of 8.9 mm length and 54 mm is reshaped into a circle , the diameter of the circle will be equal to the perimeter of the wire .
Perimeter of wire (rectangle) = 2×(l+b)
= 2 × ( 8.9 + 54 )
= 2 × 62.9 mm
=125.8 mm
Radius = 1/2 of a diameter
Hence radius of a circle with 125.8 mm diameter = 125.8÷2
= 62.9 mm
Therefore , the radius of this circle will be equal to 62.9 mm .
