Enter the dish width (in) and the dish depth (in) into the Dish Radius Calculator. The calculator will evaluate the Dish Radius. 

Dish Radius Formula

The following two example problems outline the steps and information needed to calculate the Dish Radius.

DR = SQRT (DW^2+DD^2)


  • DR is the Dish Radius (in)
  • DW is the dish width (in) 
  • DD is the dish depth (in) 

How to Calculate Dish Radius?

The following steps outline how to calculate the Dish Radius.

  1. First, determine the dish width (in). 
  2. Next, determine the dish depth (in). 
  3. Next, gather the formula from above = DR = SQRT (DW^2+DD^2).
  4. Finally, calculate the Dish Radius.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

dish width (in) = 2

dish depth (in) = 5

DR = SQRT (DW^2+DD^2) = ?
