Answer 2

Answer:The diameter measures how big the circle is from rim to rim passing through the center

Step-by-step explanation: To calculate the diameter of a circle, multiply the radius by 2. If you don't have the radius, divide the circumference of the circle by π to get the diameter. If you don't have the radius or the circumference, divide the area of the circle by π and then find that number's square root to get the radius.
