Answer:
1 : 9
Step-by-step explanation:
Given 2 similar figures with sides in ratio a : b , then
ratio of areas = a² : b²
Here the ratio of sides = 1 : 3 , thus
ratio of areas = 1² : 3² = 1 : 9
The answer would be D since x alone cannot form an expression. It can however be a term, variable, and a constant, because those all need another number to form a formal question.
The center of the circle (x + 9)² + (y − 6)² = 10² is at (-9, 6) and the radius of the circle is 10 units.
<h3>What is a circle?</h3>
It is a locus of a point drawn an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.
The equation of the circle is given as
(x + 9)² + (y − 6)² = 10²
Then the center of the circle is at (-9, 6) and the radius of the circle is 10 units.
