A piece of wire 20 m long is cut into two pieces. One piece is bent into a square and the other is bent into a circle.

Answer :

MRROYALIN

The length of the wire is the perimeter of the wire

The radius of the circle is 1.59 meters

How to determine the radius of the circle?

The length of the wire is given as:

L  = 20m

When cut into two pieces, we have:

  • Perimeter of square = 10 m
  • Circumference of circle = 10m

The circumference of the circle is calculated using:

C = 2πr

So, we have:

2πr = 10

Make r the subject

r = 10/2π

Evaluate the quotient

r = 1.59

Hence, the radius of the circle is 1.59 meters
