Edit: assuming the following (starting top left, clockwise): R4, R10, R6, R5

[area of rectangle] - [area of corner cutouts]

(20 x 30) - {[(8^2)-(pi*4^2)]/4} - [(pi*10^2)/4] - {[(12^2)-(pi*6^2)]/4} - [(pi*5^2)/4]

= 600 - (3.4) - (78.5) - (7.7) - (19.6)

= 490.8

You'd have to be assuming r in all four corners though to work that out.

correct. I updated the comment to show my assumptions.

Yes! I got this too! I'm glad I worked it out (though I got 490.66)

Is it typical to refer to the radius as R[Length]? I've never see the radius referred to this way.

Would you refer the diameters as D6, D20, etc.?

In CAD yea.

In some drafting standards yes, but I was mostly copying the format of the picture.
