In the triangles, tr = ge and sr = fe.
triangles s t r and f g e are shown. angle s r t is 56 degrees. angle f e g is 42 degrees. sides t r and g e are congruent. sides s r and f e are congruent.
if line segment g f = 3.2 ft, which is a possible measure of line segment t s?

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)
