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

what statement best describes the difference between the sympathetic and parasympathetic nervous systems?

the sympathetic nervous system prepares the body for intense physical activity and is often referred to as the fight-or-flight response. the parasympathetic nervous system has almost the exact opposite effect and relaxes the body and inhibits or slows many high energy functions.

they fuse to form they have half as many chromosomes as a somatic cell of the same individual. b
