The volume of a right circular cylinder can be approximated as follows: volume = ? r2h; where r is the radius of the cylinder and h is the height of the cylinder; ? is a constant that is roughly equal to 3. using the simple approximation above, calculate the volume of a right circular cylinder with a radius of 2 meters and a height of 9 meters.

The volume of a right cylinder is the area of the base times the height of the cylinder.

If ? = 3, r = 2m, h = 9m

The equation is ?r2h, then:

3 * m * 9m = 108 m3

supercell thunderstorms are perhaps the most violent of all thunderstorm types, and are capable of producing damaging winds, large hail, and weak-to-violent tornadoes

hydrogen is a compound or a single element and a element is a pure substence that cannot be separated into simpler subtances

clorine is a compound its a chemical substance that forms when two or more different elements combine

so both hydrogen and clorine are compounds
