One sample cup will hold 11.51 ounces of fluid.
Step-by-step explanation:
Diameter of cone shaped cup = 4 inches
Radius = 
Height of cup = 5 inches
Volume of cone = 
Putting values
Volume of cone = 
Volume of cone = 
Volume of cone = 20.93 inches cubed
Amount of fluid in one cubic inch = 0.55 ounces
Amount of fluid in 20.93 cubic inches = 0.55*20.93 = 11.51 ounces
One sample cup will hold 11.51 ounces of fluid.
So the length will be 18^2-4^2 all rooted. 18 square is 324 and 4 square is 16 and 324-16 is 308 so the answer will be the root of 308 or 2 root 77, at least that is what I think.
Because 5 is being subtracted from 1 side, do the opposite and add it to both. 61 plus 5 = 66, so D is correct.
