When standing 155 feet away from the leaning tower of Pisa (to the right with the tower leaning toward you) you
find the angle of elevation, to the top of the 183 foot tall tower, to be 53°. Assurning the tower was built to stand perpendicular with the ground, how many degrees has the tower moved from construction in 1372?

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)
