Cup Modeling (1) V2
Your task: Create a virtual model of this cup below. Keep reading below.
Measure the HEIGHT of this cup first. Make sure to hold the ruler perpendicular to your table or desk! (See pic.)
Next, measure the radius of the top opening and bottom opening of your bowl. To so do accurately, follow the instructions [size=200][b][url=https://www.geogebra.org/m/qzxmrvsp]seen here in this link[/url][/b][/size].
