The circle below is centered at the origin and has a radius of 5 what is it’s equation
2 answers:
Answer:
x^2 + y^2 = 5^2
or x^2 +y^2 = 25
Step-by-step explanation:
The equation of a circle is usually written in the form
(x-h)^2 + (y-k)^2 = r^2
Where (h,k) is the center and r is the radius
The center is at the origin so (h,k) = (0,0) and the radius is 5 so r=5
x^2 + y^2 = 5^2
or x^2 +y^2 = 25
<em>Answer: </em>
<em>x² + y² = 25</em>
<em>Step-by-step explanation: </em>
<em>(x - h)² + (y - k)² = r²</em>
<em>Center ( h⁰, k⁰) </em>
<em>radius = 5/r </em>
<em>(x - 0)² + (y - 0)² = 5² ⇒</em><em> x² + y² = 25 </em>

<em>This will be your answer : </em><em><u>x² + y² = 25 </u></em>

Draw a perpendicular segment from point C to the midpoint of AB. Using the trig sine function sin 80 = x/6 which gives 5.91 for the perpendicular segment. Using the formula A=1/2bh, A= 1/2 x5.91x2sqrt 2 A= 8.4
