A system of equations is graphed on a coordinate plane. Which coordinates are the best estimate of the solution to the
system of equations?

A (2, 3)
B (1, 2)
C (2, 2)
D (2, 4)

Solve the triangle. a = 21°, c = 105°, c = 5

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)
