You are performing two chemistry experiments. the probability that both experiments are successful is 22%. if the first experiment is successful, the probability that the second experiment is also successful is 31%. what is the probability that the first experiment is successful?

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)

Solve the formula ax+ by = c for x.
