A circular field measures 74 meters through the center, connecting two points on the circumference. What is the radius and the area of the field?

Answer 1

Since the diameter in this case is 74 meters, half of that would be the radius. So the radius is 37 meters. The area is circular so the formula for that would be pi r squared. Since we know that r is 37 meters we can plug that in to get pi times 37 squared, which is 4300.840343 meters or rounded to about 4301 meters and that is your area.
