Rowan and Brody are both solving the equation 4x = 12. Rowan is not sure what to do because he does not know a power of 4 that equals 12. Brody uses his calculator to graph y = 4x and y = 12 and find the point of intersection. Will Brody’s method work?

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)
