# Calculate Area

Calculate Area option allows the user to measure the area between two points. Similar to the Calculate Distance option, there are 3 major way to select points:

** Calculate:** To calculate the area, after setting the locations of the
points, the user should click on Calculate.

** Clear All:** To clear the points’ locations and the calculations.

X1 = 1^{st} Point’s X location

R1 = 1^{st} Point’s Y location

X2 = 2^{nd} Point’s X location

R2 = 2^{nd} Point’s Y location

Line 1: cylindrical area = 2*π*R1*(X2-X1)

Line 2: cylindrical area = 2*π*R2*(X2-X1)

Line 3: annular area = π*(R2^{2}-R1^{2})

Line 4: conical area =
