What is one-eighth of r?
One-eighth of a quantity ( r ) can be calculated by dividing ( r ) by 8. Mathematically, it can be represented as ( \frac{r}{8} ). This means that if you have a value for ( r ), you can find one-eighth of that value by simply dividing it by 8.
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.
If the diameter is 17 what is the area?
The formula for the area of a circle is r*r*pi, where r is radius. Radius is half of the diameter, so to find the area you first need to find half of 17. 17/2=8.5 Then put that in the formula to find the answer. 8.5*8.5*3.14=226.865 with a more accurate value for Pi you get 226.98
