Question:

How do you convert the polar equation #r=3# into rectangular form?

Answers

#x^2+y^2=9#

Explanation:

#color(orange)"Reminder"#

#• r=sqrt(x^2+y^2)#

#rArrsqrt(x^2+y^2)=3#

#"squaring both sides"#

#rArrx^2+y^2=9larr" in rectangular form"#

#"this is the equation of a circle, centred at O, with radius 3"#
