A circular lampshade with a diameter of 14 inches has a length of wire that goes around it exactly one time. How many inches of wire are needed to go around the lampshade exactly one time?
Diameter = 2*radius 14/2=7 Radius is 7in" Circumference of circle formula: 2pi(radius) 2pi(7)= 43.98in of wire required so it can wrap around lamp exactly once.
