Question:

The diameter of bicycle wheel is 20 in.what is the area of the wheel?

Given: d= 20 in

since the radius is half of the diameter that is,

r=½d

r=½(20in)

r= 10in

Step by step Explanation:

A=πr²

=3.14(10in²)

=3.14(100in)

=314 in²

Therefore, the are of the bicycle wheel is 314 in².
