Question

What is the area of the circle in terms of PI?

Answer 1

To find the area of the circle:

⇒ must know the area's formula ⇒
`\pi r^2`

• r --> length of radius

Let's consider the information given

• diameter's length is 7 in

⇒ the radius' length is half of the diameter

⇒ thus the radius' length is 3.5 in

Let's calculate the area:

`Area=\pi r^2=\pi (3.5^2)=12.25\pi in^2`

The problem asks us to leave the answer in terms of '
`\pi`' which means that we won't multiply '
`\pi`' to the final answer, but leave it there,

Answer: 12.25
`\pi in^2` or Choice (B)

Hope that helps!
