Area of a Rounded Corner Rectangle formula |
||
\( A_{area} \;=\; a \cdot b - r^2 \cdot \left( 4 - \pi \right) \) | ||
Symbol | English | Metric |
\( A_{area} \) = area | \( in^2\) | \( mm^2 \) |
\( r \) = corner radius | \( in\) | \( mm \) |
\( a, b, c, d \) = edge | \( in\) | \( mm \) |
\( \pi \) = Pi | \(3.141 592 653 ...\) | \(3.141 592 653 ...\) |
Diagonal of a Rounded Corner Rectangle formula |
||
\( D' \;=\; \sqrt{ \left( a - 2\cdot r \right)^2 + \left( b - 2\cdot r \right)^2 } + 2\;r \) | ||
Symbol | English | Metric |
\( D' \) = diagonal | \( in\) | \( mm \) |
\( r \) = corner radius | \( in\) | \( mm \) |
\( a, b, c, d \) = edge | \( in\) | \( mm \) |
Perimeter of a Rounded Corner Rectangle formula |
||
\( p \;=\; 2 \; \left[ a + b - r^2 \cdot \left( 4 - \pi \right) \right] \) | ||
Symbol | English | Metric |
\( p \) = perimeter | \( in\) | \( mm \) |
\( r \) = corner radius | \( in\) | \( mm \) |
\( a, b, c, d \) = edge | \( in\) | \( mm \) |
\( \pi \) = Pi | \(3.141 592 653 ...\) | \(3.141 592 653 ...\) |
