Set ? as x, and cross-multiply.
so x^2= 36
x = 6 or x = -6
<h2>
<em>Answer</em></h2>
<em>361</em><em>π</em><em>km²</em>

<em>Explanation</em></h2>
• the formula to find the area of a circle is A=πr²
<h3> =>
<em>A=π(19km)²</em></h3><h3>
<em>A=π(19km)² => A=361πkm</em>²</h3><h2>

The answer would be -10 if you want me to explain tell me to <span />
The correct answer is 25 cm². The area of a square is l x w, and, since each of the sides is the same length, the formula is 5 x 5.
A = lw Formula for a square
A = (5)(5)
A = 25
The area is 25 cm².
Hope this helps!
