Question

At the bakery where Paul works, one of the cups in a cupcake tray has a radius of 1 inch. What is the cup's circumference?

Use 3.14 for π. If necessary, round your answer to the nearest hundredth.____inches

Answer 1

To find the circumference of a cup with a radius of 1 inch, you multiply the radius by 2 and by π (3.14), resulting in a circumference of 6.28 inches, which remains the same when rounded to the nearest hundredth.

Step-by-step explanation:

The question asks us to determine the circumference of a cup with a radius of 1 inch, using 3.14 for π (π). The formula to find the circumference (C) of a circle is C = 2πr, where r represents the radius. In this case, the radius (r) is 1 inch, so using the given value for π (3.14), the calculation would be:

C = 2 × 3.14 × 1 = 6.28 inches

If rounding is necessary, the circumference of 6.28 inches remains the same when rounded to the nearest hundredth, as there are no additional digits beyond the hundredth place.
