Question

The circumference of the flotation device above is 62.8 inches. If three flotation devices are lined up end-to-end, then what is the length of the flotation devices?

Answer 1

Find the diameter by dividing the circumference by PI:

Diameter = 62.8 / 3.14 = 20 inches.

There are 3 lined up so multiply the diameter by 3:

20 x 3 = 60 inches. (5 feet)
