Question

What is the circumference of a circle with a diameter of 4.1 cm? Use 3.14 for pi. Enter your answer as a decimal in the box.

Answer 1

Explanation:

C = 3.14 × d

3.14 × 4.1

= 12.874

Answer 2

12.874 cm

Explanation:

The circumference of a circle is:
`C = 2\pi r=\pi d` , where r is the radius and d is the diameter.

Here, we're given that the diameter is 4.1 and that we will use 3.14 for
`\pi`. So, plug these in:

`C=3.14*4.1=12.874`

Thus, the answer is 12.874 cm.

Hope this helps!
