Answer: The diameter of the circle is 20 cm.
Step-by-step explanation:
Since we have given that
Area of circle = 4 times larger than the circumference of that same circle.
Mathematically, it is expressed as
[tex]\pi r^2=5\times 2\pi r\\\\\pi r^2=10\pi r\\\\r=10\ cm\\\\Diameter=2\times radius\\\\Diameter=2\times 20\\\\Diameter=20\ cm[/tex]
Hence, the diameter of the circle is 20 cm.
