Question

Ruby is visiting a wildlife center to gather information for her term paper. The center has a circular pond with a diameter of 20 meters. What is the approximate area of the pond?

Answer 1

Well , the diameter means a straight line passing from side to side through the center of a body or figure, especially a circle or sphere. The area means what the extent or measurement of a surface or piece of land. So area means inside so all you need to do is  just to divide each side by knowing what 20/4 is and that = 5 meters
