The following differential equation describes the dynamics of an experimental yeast population: dN dt = (0.59 − 0.0026N)N where N(t) is the population size (in millions of individuals per mL) at time t (in hours). Sketch the direction field of the differential equation for values of N between 0 and 250.

Circle a has a diameter of 7 inches, a circumference of 21.98 inches, and an area of 38.465 square inches. the diameter of circle b is 6 inches, the circumference is 18.84 inches, and the area is 28.26 square inches. part a: using the formula for circumference, solve for the value of pi for each circle. (4 points) part b: use the formula for area and solve for the value of pi for each circle. (4 points)
