Question

The diameter of a circle is 16 ft. Find its area to the nearest whole number

Answer 1

Answer: 201 ft

Explanation:

Circle area = 3.14 * 8² = 3.14 x 64

3.14 x 8² = 200.96 ft²

Answer 2

Hello !

Answer:

`\boxed{\sf A_(circle)\approx 201\ ft^2}`

Explanation:

The area of a circle is given by the following formula :

`\sf A_(circle)=\pi * r^2`

Where r is the radius.

Given :

• Diameter : d = 16ft

We know that the radius is half the diameter.

So
`\sf r=(d)/(2) =(16)/(2) =\underline{8ft}`.

Let's substitute r whith it value in the previous formula :

`\sf A_(circle)=\pi* 8^2\\\boxed{\sf A_(circle)\approx 201\ ft^2}`

Have a nice day ;)
