WebMar 30, 2024 · Now , for a unit circle , the terminal side of angle θ is ( cos θ , sin θ ) Given data , Let the diameter of the circle be d = 63 cm. The circumference of a circle is given by the formula: C = πd. where d is the diameter of the circle and π is the mathematical constant pi, approximately equal to 3.14159. C = π(63) C = 197.92 cm WebThe ratio of the circumference to the diameter of any circle is a constant known as pi (π), which is equal to approximately 3.14159. From this relationship, we can derive the formula for the circumference of a circle: C = πd. where C is the circumference and d is the diameter of the circle. Using radius instead of diameter, the formula is: C ...
