Answer: The diameter of the circle is 20 cm.

Explanation:

Since we have given that

Area of circle = 4 times larger than the circumference of that same circle.

Mathematically, it is expressed as


\pi r^2=5* 2\pi r\\\\\pi r^2=10\pi r\\\\r=10\ cm\\\\Diameter=2* radius\\\\Diameter=2* 20\\\\Diameter=20\ cm

Hence, the diameter of the circle is 20 cm.
