Question

What is the area of a circle with a radius of 12 feet?

Answer 1

144π ft² or approximately 452.16 ft²

Explanation:

The area of a circle is
`\pi r^2`, where r = radius. We're given the radius as 12 feet. For pi, we can solve area in terms of pi or approximate pi to 3.14.

Approximation of Pi:

• 
  `3.14 *12^2`
• 
  `3.14*144`
• 
  `452.16`
• 452.16 ft²

In terms of Pi:

• 
  `\pi *12^2`
• 
  `\pi *144`
• 
  `144\pi`
• 144π ft²

Answer 2

`144 * \pi = 452.38`
