1. A surveyor starts at the edge of a lake, at point A, and measures a 90° angle between B and C, as shown. The surveyor then walks 95 meters to B and measures an angle of 79° between A and C. Approximately how
many meters wide is the lake between A and C. Round your answer to the nearest hundredth if necessary.

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)
