Question

Susan is making circular placemats for her kitchen table. The diameter of the circle is 5.6 inches. She wants to place a decorative ribbon around the outside of the circle. How much ribbon does she need, rounded to the nearest inch?

Answer 1

17.6
Rounded to the nearest inch would be 18

Answer 2

18 inches

Explanation:

To find the length of ribbon Susan needs, she can use the formula for the circumference of a circle:

C = πd

where C is the circumference, d is the diameter, and π is approximately 3.14.

Plugging in the given diameter of 5.6 inches, we get:

C = πd

C = 3.14 × 5.6

C ≈ 17.6

Therefore, Susan needs approximately 17.6 inches of ribbon rounded to the nearest inch. Rounded to the nearest inch, the answer is 18 inches.
