just add up their circumferences.
recall that circumference of a circle = π(diameter)
so we have
3π + 3.2π + 2.8π + 3.5π + 2.9π
= π(3+3.2+2.8+3.5+2.9)
= .....
Onion rings vary in size. The five rings in the graphic at the top of the page have diameters of 3 inches, 3.2 inches, 2.8 inches, 3.5 inches and 2.9 inches. If it were possible to straighten out the rings, and lay them end to end, how long would this line of onion rings be, to the nearest tenth of an inch?
