Write an expression to solve for the radius of an object with a circumference of 30 feet.

c i rc u m f ere n ce = 30 f t . c i rc u m f ere n ce = 2 π r ( r − r a d i u s ) 2 π r = 30 / : 2 π r = 2 π 30 ​ r = π 15 ​ ( f t ) π 15 ​ ≈ 3.14 15 ​ ≈ 4.78 ( f t )

C=2pi(r) 30=2pi (r) r=(30)/(2pi)

To find the radius of an object with a circumference of 30 feet, use the formula r = 2 π 30 ​ . This simplifies to approximately 4.78 feet when using π ≈ 3.14 . Therefore, the radius is about 4.78 feet.
