Answer:
x²+(y-5)²=25
Step-by-step explanation:
To convert polar into rectagular
![->r=\sqrt{x^2+y^2} =>r^2=x^2+y^2\\](https://tex.z-dn.net/?f=-%3Er%3D%5Csqrt%7Bx%5E2%2By%5E2%7D%20%3D%3Er%5E2%3Dx%5E2%2By%5E2%5C%5C)
also, y=rsin θ => sin θ=y/r
r= 10sinθ
r=
=> r²=10y
therefore, x²+y²-10y=0
By completing the squares on y²-10y gives
x²+(y-5)²=25
which is the equation of the circle.
This is the Cartesian equation of a circle with center (
0,
5)
and radius, r=5
Definitely an easy question, just remember "3,4,5 triangle" Answer is C. <span />
