Formula
------------------------------------------------------
Circumference = πD

------------------------------------------------------
Find 1 revolution
------------------------------------------------------
Circumference = π x 20
Circumference = 62.83 inches

------------------------------------------------------
Find 3 revolutions
------------------------------------------------------
1 revolution = 62.83
3 revolutions = 62.83 x 3
3 revolutions = 188.50 inches

------------------------------------------------------
Convert inches to feet
------------------------------------------------------
12 inches = 1 foot
188.50 ÷ 12 = 16 feet (nearest foot)

------------------------------------------------------
Answer: Annie will travel 16 feet in 1 second
