Question

If a circle has a diameter of 24 inches, which expression gives its area in
square inches?​

Answer 1

D

Explanation:

The formula for the area of a circle is pi times radius squared.

The radius is half of the diameter, so 24/2 = 12

12^2 x pi

Answer 2

`12^2 \pi`

Explanation:

Since, the area of a circle,

`A=\pi r^2`

Where,

r = radius of the circle,

Given,

Diameter of the circle = 24 inches,

So, the radius of the circle, r =
`(Diameter)/(2)` =
`(24)/(2)` = 12 inches,

Thus, the area of the circle is,

`A=12^2 \pi \text{ square inches}`

OPTION D is correct.
