Drywall provides an R-value of 0.32 for 3/8" board, 0.45 for 1/2" board, 0.56 for 5/8" and 0.83 for 1" board. In addition to increased R-value, thicker drywall has a higher STC.

U value of r-19 insulation?
The U value is the inverse of the R value. For R value 19 insulation the U value is 1/19, or 0.0526.

Surface area of sphere with volume 0.2 meters?
For the question to have any meaning, the volume should be in cubic metres, not metres. The surface area of a sphere of radius r is 4*pi*r*r and its volume is 4/3*pi*r*r*r. Use the second equation to find the value of the radius, r and then use that value in the first equation to calculate the surface area.
Is dry wall an insulator?
While drywall, or gypsum board, does give insulation value it is not a high amount, a 1/2" piece of drywall will only raise the r-value by .45, if you are looking to improve the insulation of a wall you are much better off using rigid foam insulation. An extruded polystyrene board, that's Styrofoam, of 1" thickness gives you an R-value of 5.00, which is over 5 times greater per inch than that of drywall. You can further improve the insulation value of a wall by add some kind of batt insulation in-between the studs.
What is white drywall?
White drywall is just normal everyday drywall.
U value of r-19 insulation?

The effectiveness of insulation is rated with?
I want to say either R-Value or Temperature Value? Probably R-Value... Out of answers: a. convection value b. R-value c. temperature value d. solar value
Is a material with a lower R-value a better insulator than a material with a high R-value?
No. A higher R-value is a better insulator.
