Answer: To find the cost to print a circular frame, we need to first find the area of circle.

Given: r=1.1

We know that:

Area of circle =\pi \times r^{2}

                       =3.14 \times 1.1^{2}

                       =3.7994

Also we are given cost per square foot is $27

Therefore, the cost to print a circular sign with a radius of 1.1 feet is:

3.7994 \times 27= 102.58  or $102.58
