Pi is approximately 3.14 and is basically the circumference of a circle divided by the diameter. This value, known as "pi", is constant throughout every circle. Pi is used to calculate the circumference and area of a circle, among many other things.

A bicycle wheel has a diameter of 24inches. 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

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

ruslelena [56]

Answer: option B is the correct answer

Step-by-step explanation:

Candace's backyard has a flower garden that covers 40% of her backyard.

If the total area of her backyard is 450 square feet, it means that her garden covers 40% of 450 square feet.

To determine how many square feet is her flower garden, we will find the value of 40% of 450 square feet. It becomes

40/100 × 450= 0.4×460 = 180 square feet
