Find an equation equivalent to r=10 sin in rectangular coordinates

Answer:
D. [tex]x^{2} + y^{2} = 10\cdot y[/tex]
Step-by-step explanation:
The equvalent form of the equation is:
[tex]\sqrt{x^{2}+y^{2}} = 10\cdot \left(\frac{y}{\sqrt{x^{2}+y^{2}}} \right)[/tex]
[tex]x^{2} + y^{2} = 10\cdot y[/tex]
The answer is D.
