Answer:
The diameter of bicycle wheel is:
7 ft.
Step-by-step explanation:
The distance around a bicycle wheel is 21.98 feet.
this implies that circumference of the bicycle wheel is 21.98 feet
we know that the circumference of a circle is given by the formula:
C = 2πr
where 'r' is the radius of the circle.
⇒ 21.98=2×3.14×r
⇒ r=3.5 ft.
Now we know that diameter of circle is twice the radius of the circle.
⇒ d=2r
⇒ d=2×3.5
⇒ d=7 ft.
Hence, the diameter of bicycle wheel is:
7 ft.
