A circular pool has a radius of 12 feet. What is the
approximate distance around the pool

Solve this equation using substitution. {4x + y = −2} {4x + 6y = 44}

The standard deviation for a set of data is 5.5. the mean is 265. what is the margin of error?

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)
