Question

the area of circle is 616 cm² find its diameter​

Answer 1

Answer:

The diameter is 28cm and the circumference is 88cm

Step-by-step explanation:

Calculate the Diameter of a Circle, from Its Area

Divide the area (in square units) by Pi (approximately 3.14159). Example: 303,000/3.14159 = 96447.98.

Take the square root of the result (Example: 310.56). This is the radius.

Now double the radius to get the diameter (Example: 621.12 meters).
