A bicycle wheel has a diameter of 24inches. <br> what is the area of the wheel?

goldfiish [28.3K]

Answer:

$\large\boxed{A=144\pi\ in^2\approx452.16\ in^2}$

Step-by-step explanation:

A diameter is two times longer than a radius. Therefore, if the diameter

d = 24in, then the radius r = (24in) : 2 = 12in.

The formula of an area of a circle:

$A=\pi r^2$

Substitute:

$A=\pi(12)^2=144\pi\ in^2$

$\pi\approx3.14$

Then

$A\approx(144)(3.14)=452.16\ in^2$
