Answer:
The length of the radius of the circle is [tex]4 cm[/tex].
Step-by-step explanation:
Given that,
Area of Yellow paint is needed for one of the circle is [tex]50.24\ cm^{2}[/tex].
To find:- What is the length of the radius of the radius of the circle?
From the Question,
Area of circle = [tex]\pi r^{2}[/tex], where r is the radius of circle.
So, [tex]\pi r^{2} = 50.24[/tex]
[tex]r^{2} = \frac{50.24}{3.14} \\r^{2} = 16\\ r= \sqrt{16} = 4\ cm[/tex]
Therefore, The length of the radius of the circle is [tex]4 cm[/tex].
This is the Required radius of circle = [tex]4 cm[/tex] for the give area [tex]50.24\ cm^{2}[/tex].
