Question

A circular dog bed has a

circumference of about 72 inches. What
is the diameter in inches of the dog bed
to the nearest inch?​

Answer 1

23 inches

Explanation:

Circumference = 2πr

72 = 2×3.142×r

Divide through by 2 × 3.142

r =
`(72)/(2 * 3.142)`

r = 11.458 inches

Diameter = 2r

Diameter = 2* 11.458 = 22.92

= 23 inches to the nearest inch
