Pre algebra questions,

1)The circumference of a circle of radius r is given by the polynomial 2πr, where π is an irrational number. Use 3.14 as an approximation of π, and find the circumference of a circle with radius 4 in.

2) find a polynomial for the perimeter of the figure ( attached on file) show work for this

3)An object's altitude, in meters, is given by the polynomial h+vt−9.8t^2, where h is the height in meters from which the launch occurs, v is the initial upward speed in meters per second, and t is the number of seconds for which the rocket is airborne. A pebble is shot upward from the top of a building 103 meters tall. If the initial speed is 49 meters per second, how high above the ground will the pebble be after 2 seconds?Round results to the nearest tenth of a meter.

4) X^2-11 / X-4 show work for this

5) 6.3 x 10^-2 / 3 x 10 ^-6 show work for this

6) 30m^7n-18m^6n^3+42m^5n^5 / 6m^4n show work for this
