If the radius of the circular table is 5 cm then the length of the trim required is 31.4 cm.
Given that the radius of the circular table is 5 cm.
What is the length of trim needed to decorate along the outside trim?
Circumference is the length of arc of the circle.It is also known as the perimeter of the circle.
Circumference of the circle=2πr in which r is the radius of the circle.
It is given that the trim is placed and decorated along the outside edge, so the perimeter of the circle must equal to the length of trim needed.
Length of trim needed to decorate the circular table=2πr
=2*π*5
=10π
=10*3.14
=31.4 cm.
Hence the length of the trim needed to decorate along the table is 31.4 cm.
