We can use trig ratios to find unknown sides in right triangles. Let's look at an example.
Given \triangle ABC△ABCtriangle, A, B, C, find ACACA, C.

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)

Which best explains why this triangle is or is not a right triangle ?
