Question

Find the area of a circle with the diameter of 2 inches.

Answer 1

`\pi \text{ in}^2` or
`\pi \text{ square inches}`

Explanation:

Area of a Circle:

The area of a circle can be calculated using the formula:
`A=\pi r^2`, where "r" is the radius. The radius is the distance from the center of the circle to any point on the circle, which can also be defined as half the diameter.

The diameter provided is 2 inches and half of that is 1 inch meaning the radius is equal to 1 inch. Now we can just plug this into our formula:
`A = \pi (1\text{ in})^2=\pi \text{ in}^2`
