Understanding Water Drainage: 20% of 45π Equals 9π Cubic Meters When managing water resources—especially in construction, landscaping, or flood prevention—it’s essential to calculate precise volumes of water that need to be drained. A common scenario involves draining exactly 20% of a volume represented as 45π cubic meters. Understanding this calculation not only clarifies resource allocation but also supports efficient project planning. ### The Basic Calculation To find 20% of a given value, multiply by 0.2 (or 0.2 × the total). In this case:
