Given:
Radius (r) = 4.5 inches
Circumference formula:
C = 2πr
Substitute the value of r:
C = 2π(4.5)
C = 2 x 3.14 x 4.5
C = 28.26 inches
Desirae will need a rope with a length of 28.26 inches.
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.
