Algorithm:

Step $0$: Start

Step $1$: Initialize GeometricalApp Class

Step $2$: Create a dictionary of geometrical calculations with names and details

Step $3$: Initialize an empty list to store user inputs

Step $4$: Display Available Calculations

Step $5$: Print "Available Geometrical Calculations:" and iterate through each calculation in the calculations dictionary

Step $6$: Display calculation code, name, and details

Step $7$: Allow Users to Select Calculations

Step $8$: Display a welcome message for the Geometrical Application

Step $9$: Execute a loop until 'done' is entered

Step $10$: Prompt the user to enter a calculation code or 'done' to complete

Step $11$: If 'done' is entered, exit the loop

Step $12$: Prompt the user to enter the required parameters for the selected calculation

Step $13$: Add the selected calculation and its parameters to the list using the add to list method

Step $14$: Perform Calculations and Display Results

Step $15$: Iterate through the list of user$-$selected calculations and parameters

$-$Step $16$: Perform each geometrical calculation and store the result

Step $17$: Display the result of each calculation

Step $18$: Calculate Area

Step $19$: Prompt the user to enter the dimensions for area calculation $($e$.$g$.,$ length and width for a rectangle$)$

Step $20$: Perform the area calculation

Step $21$: Display the calculated area

Step $22$: Calculate Perimeter

Step $23$: Prompt the user to enter the dimensions for perimeter calculation $($e$.$g$.,$ sides of a polygon$)$

Step $24$: Perform the perimeter calculation

Step $25$: Display the calculated perimeter

Step $26$: Calculate Volume

Step $27$: Prompt the user to enter the dimensions for volume calculation $($e$.$g$.,$ radius and height for a cylinder$)$

Step $28$: Perform the volume calculation

Step $29$: Display the calculated volume

Step $30$: Calculate Surface Area

Step $31$: Prompt the user to enter the dimensions for surface area calculation $($e$.$g$.,$ radius for a sphere$)$

Step $32$: Perform the surface area calculation

Step $33$: Display the calculated surface area

Step $34$: Stop
