Ana is planning to plant roses around the edge of a circular flowerbed having a diameter of 7 feet. if the total cost of planting roses is $176, what is the unit price of planting roses per foot? (use π=227.)

i belive those are the ones that are under 90 degreese.

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
