Rodney needs to create a model to represent his sample space of the experiment. In the model he will use the following abbreviations: H = heads, T = tails, R = red, B = blue, and G = green. Which model could Rodney use to best represent the sample space for his experiment?

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)
