If the area of a circle is 31.36 pi, then what is its radius?

Sagot :

Answer:

5.6 units

Step-by-step explanation:

[tex]\boxed{area \: of \: circle = \pi {r}^{2} }[/tex]

Given that the area of the circle is 31.36π,

31.36π= πr²

Divide both sides by π:

31.36= r²

r²= 31.36

Square root both sides:

[tex]r = \sqrt{31.36} [/tex]

r= 5.6 units
