Consider the diagram. Triangles L O N and L M N share side L N. Sides O L and M L are congruent. Sides O N and N M are congruent. The congruence theorem that can be used to prove △LON ≅ △LMN is SSS. ASA. SAS. HL.

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)
