Question

The distance around a bicycle wheel is 21.98 feet.what is its diameter

Answer 1

Circumference = pi*diameter
circumference = 21.98

so diameter = circumference divided by pi
= 21.98 / 3.14 = 7

Therefore the Diameter of the Bicycle wheel is 7 feet

Answer 2

The diameter of bicycle wheel is:

7 ft.

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.
