The formula to find the area of a circle is: π r squared. So, 4.5 π squared = about 63.62

Area = π . r² = 3.14 × 4.5² = 63.62 square units.
<span>In terms of circumference:</span>

Area = <span>C2</span>/(4π) = <span>28.272</span>/4π = 799.19/(4 × 3.14) = 799.19/(12.56) = 63.62 square units.

<span>I hope this helped.... ;)

Explain the error in my screenshot
serious [3.7K]

Step-by-step explanation:

The domain of a function is all possible input x-values, and the range of function is all possible output y-values.

The domain of this function is (-6, 3) and the range is (-5, 5). Those are written like this:

D: (-6, 3)

R: (-5, 5)

I suppose I'll pick the first one: "The domain is (-6, -1)." This is wrong as the domain on the graph shown is (-6, 3).
