Question

Rewrite in rectangular form: r=5

Answer 1

x^2+y^2=25

Explanation:

100% correct

Answer 2

x ^2+ y^ 2 = 25

Explanation:

Square both sides:

r ^2 = 5^ 2

Substitute x ^2 + y^ 2 for r ^2 :

x ^2+ y ^2 = 5 ^2

Insert the center -0 into the x and y terms:

( x − 0 )^ 2 + ( y − 0 ) ^2 = 5 ^2

This is the standard form for a circle whose center is ( 0, 0 ) and the radius is 5.
