Hi, I'm Drew Moyer and this is how to figure the area and volume of a pond. Finding the area and volume for irregular shapes is a difficult task and often involves dividing the shape into several known shapes or approximating the irregular shape into a shape that it closely resembles. Let's suppose I have this pond and right off the bat I can say that it closely resembles a circle. So I can approximate the area by using the formula A equals Pi R squared. So for the radius I know that the pond is 72 yards lengthwise and 80 yards width-wise so what I would do is to average the two together to get an approximate radius and the average between 72 and 80 is 76. So I'm going to plug in 76 for R. A equals Pi times 76 squared and then from there it's just solving. A equals Pi times 5776 and A equals approximately 18,136.44 yards squared. And determining the volume is even easier because all I have to do is multiply my surface area which I've already gotten times the average depth which is 8. So volume equals 18,136.44 times 8 and our volume is approximately 145,093.12 cubic yards. I'm Drew Moyer, and this is how to figure the area and volume of a pond.
