Q:
# Find the radius of the circle whose equation is x^2 + y^2 = 4.

Accepted Solution

A:

Answer:Radius of the given circle is r = 2.Step-by-step explanation:Given equation of the circle is [tex]x^2 + y^2 = 4[/tex].Now we need to find the radius of the given circle [tex]x^2 + y^2 = 4[/tex].To find that let's compare with the formula of the circle with is [tex]x^2 + y^2 = r^2[/tex], where r is the radius.We get [tex]r^2 = 4[/tex]take square root of both sides.[tex]r=2[/tex]Hence radius of the given circle is r = 2.
