The volume of a cylinder of radius r and height h is v=πr2h. calculate the percentage increase in v if r is increased by 3.6% and h is increased by 4.1%.hint: use the linear approximation to show that δvv≈2δrr+δhhδvv×100%= %the volume of a certain cylinder v is determined by measuring r and h. which will lead to a greater error in v: a. a 1% error in hb. a 1% error in r is equivalent to a 1% error in hc. a 1% error in r

City l has a temperature of −3 °f. city m has a temperature of −7 °f. use the number line shown to answer the questions: number line from negative 8 to positive 8 in increments of 1 is shown. part a: write an inequality to compare the temperatures of the two cities. (3 points) part b: explain what the inequality means in relation to the positions of these numbers on the number line. (4 points) part c: use the number line to explain which city is warmer. (3 points)
