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 = 2r. (1 point)
what’s the answer
The circumference of the clock is calculated using the formula C = 2πr. Given that the radius is 4.5 inches, we can plug in the value and calculate the circumference.
C = 2π(4.5)
C = 2 x 3.14 x 4.5
C = 28.26 inches
Therefore, Desirae will need a rope that is approximately 28.26 inches long to glue along the outer edge of the clock.
