Question

The size of a bicycle is determined by the diameter of the wheel. You want a 24-in bicycle for Christmas. What is the circumference of one of the wheels? A 75.4 in B 75.3 in C 37.7 in D 37.6 in

Answer 1

Answer:

The circumference of one of the wheels is:  

                     Option: A    75.4 in.

Step-by-step explanation:

The 24-in bicycle means that the diameter of the wheel of the bicycle isL 24 in.

We know that the wheel of the bicycle is in the shape of a circle.

This means that the diameter of circle is: 24 in.

Hence, the radius(r) of circle is: 12 in.

( since we know that the radius(r) of the circle is half the diameter(d) of the circle)

Now, we are asked to find the circumference of the circle.

The circumference(C) of the circle is given by:

C=2πr

i.e.

C=2×3.14×12

i.e.

C=75.36 in.

which to the nearest tenth is: C=75.4 in.
