Desirae purchased a circular clock with a radius of 4.5 inches. She is going to glue a rope along the outer edge of the clock as decoration. Find the length of the rope that Desirae will need. Use the circumference formula: C=2πr .

Answer 1

Given that the radius of the clock is 4.5 inches, we can plug this value into the circumference formula to find the length of the rope needed.

C = 2π(4.5)
C = 9π

Therefore, Desirae will need 9π inches of rope to glue along the outer edge of the clock as decoration.
