To find a Circumference is the diameter times pie or the radius times 2 then times pie.
Remember: Pie = 3.14
Here's a example:
Radius: 8×2(3.14)
Diameter: 16(3.14)
To find the area is
A=pie×The radius squared by two

(√5 + 4)(√5 - 2)
<u>Step 2: Simplify</u>
- Expand [FOIL]: (√5)² - 2√5 + 4√5 - 8
- Combine like terms: (√5)² + 2√5 - 8
- Evaluate exponents: 5 + 2√5 - 8
- Combine like terms: 2√5 - 3
