Will vote brainiest if correct(must be next few minutes): the formula for the area of circle a is area=πr2 . sector cab is a fraction of circle a. in degrees, the fraction is θ/360∘ . in radians, the fraction is inserting this fraction into the formula for the area of a circle, and then simplifying, results in the formula (image attached) choices: 2pi0, 0pi, 0/2pi, area=0r^2, area= 2pi0r^2, area= 0/2r^2

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?
