find the diameter of the sphere whose total surface area is 14519.36 cm 2 . (use 𝜋 = 3.14) solution: let r be the radius of the sphere. the total surface area of the sphere = 4𝜋r 2 = 14519.36 cm 2 ⇒ r 2 = (14519.36)/( 4 × 3.14) = 1156 ⇒ r = √1156 = 34 ...
The volume of a cylinder of radius r and height h is V = πr^2h. Learn the formulas for the volumes of different types of cylinders along with a few solved examples.
If we know the circumference of a circle, can we find its diameter and its area? Let us find out. We know that diameter of a circle is twice its radius. This means that if “ r “ is the radius of the circle and “ d “ is the diameter of the circle, then, d = 2 r Also,...
The elapsed-time and run-length calculator is very practical for those in everyday production. Depending on the spool type, you can read the spool weight and elapsed run-times at different speeds. In addition, information is displayed on the respective wire diameter and the running length of ...
Example 4:The height and diameter of an oxygen cylinder are 20 inches and 100 inches, respectively. Find the quantity of oxygen that this cylinder can contain in cubic inches. Solution: Radius of the cylinder (r) =20 inches Height of the cylinder (h) = 100 inches ...
Calculate Density Using Volume of a Cylinder A typical test tube has a rounded bottom, but NMR tubes and certain other test tubes have a flat bottom, so the volume contained in them is a cylinder. You can get a reasonably accurate measure of volume by measuring the internal diameter of the...
