Answer:
[tex]r=5\sqrt{5}[/tex]
Step-by-step explanation:
we are given as
(x, y), = (5, 10)
we can compare
x-value is 5
[tex]x=5[/tex]
y-value is 10
[tex]y=10[/tex]
now, we can use formula
[tex]r=\sqrt{x^2+y^2}[/tex]
now, we can plug values
[tex]r=\sqrt{5^2+10^2}[/tex]
[tex]r=\sqrt{25+100}[/tex]
[tex]r=\sqrt{125}[/tex]
so, we get
[tex]r=5\sqrt{5}[/tex]
