["How to Calculate Height Using the Pythagorean Theorem: Step-by-Step Example", "Understanding how to calculate height is essential in many real-world applications—from architecture and engineering to physics and DIY home projects. One of the most powerful and widely used methods involves the Pythagorean theorem:\n[\nh = \sqrt{l^2 - r^2}\n]\nThis formula helps determine height ((h)) when you know the base length ((l)) and the radius or horizontal distance ((r)) from the center point. Below, we break down the calculation step by step, using a clear example to solidify your understanding.", "---", "### What Is the Formula for Finding Height?", "The formula ( h = \sqrt{l^2 - r^2} ) applies when dealing with right triangles—specifically, a triangle formed by the height, a horizontal distance, and a slant or hypotenuse.\n- ( l ) represents the hypotenuse (total length from top center to outer edge),\n- ( r ) is the radius or horizontal length from the center to the projection point,\n- ( h ) is the vertical height we want to find.", "This principle is commonly used in construction, roofing, and physics problems involving inclined surfaces.", "---", "### Step-by-Step Calculation Example", "Let’s solve the classic problem:\nGiven:\n- Base radius ( r = 9 ) units\n- Total length ( l = 25 ) units\nFind: Height ( h )", "Step 1: Plug values into the formula\n[\nh = \sqrt{l^2 - r^2} = \sqrt{25^2 - 9^2}\n]", "Step 2: Compute squares\n[\n25^2 = 625, \quad 9^2 = 81\n]", "Step 3: Subtract\n[\n625 - 81 = 544\n]", "Step 4: Take the square root\n[\nh = \sqrt{544}\n]\nTo simplify:\n[\n\sqrt{544} = \sqrt{16 \ imes 34} = 4\sqrt{34}\n]\nWhile exact form is useful, decimal approximation is practical for most applications:\n[\n\sqrt{544} \approx 23.32\n]", "So, the height is approximately ( 23.32 ) units.", "---", "### Why This Formula Works", "The Pythagorean theorem states in a right triangle, the square of the hypotenuse exceeds the sum of the squares of the other two sides. Here, the full reach (length ( l )) is the hypotenuse, the radius (( r )) forms one leg, and the actual vertical height (( h )) is the other leg.
