What is the formula for the volume of a cylinder? how did you get that? a) v = πr2 h; the area of the circle base times the height of the cylinder b) v = πr2 h; the circumference of the circle base times the height of the cylinder c) v = 2πrh+2πr2; the area of the circle bases plus the area of the unfolded rectangle d) v = 2πrh+2πr2; the circumference of the circle bases plus the area of the unfolded rectangle

Data from 2005 for various age groups show that for each $100 increase in the median weekly income for whites, the median weekly income of blacks increases by $105. also, for workers of ages 25 to 54 the median weekly income for whites was $676 and for blacks was $527. (a) let w represent the median weekly income for whites and b the median weekly income for blacks, and write the equation of the line that gives b as a linear function of w. b = (b) when the median weekly income for whites is $760, what does the equation in (a) predict for the median weekly income for blacks?
