WebSep 12, 2024 · We know the dimension of area is L 2. Now, the dimension of the expression πr2 is [πr2] = [π] ⋅ [r]2 = 1 ⋅ L2 = L2, since the constant π is a pure number and the radius r is a length. Therefore, πr2 has the dimension of area. Similarly, the dimension of the expression 2πr is [2πr] = [2] ⋅ [π] ⋅ [r] = 1 ⋅ 1 ⋅ L = L, WebMay 11, 2024 · Units and Measurement 03 Dimensional Analysis : Deriving the Formula of any Physical Quantity Physics Wallah - Alakh Pandey 9.98M subscribers Join Subscribe 101K Share Save …
