Answer
The circumference of the circle is approximately 98.0 cm.
Solution
We know that the circumference of a circle is given by the formula:
Circumference = 2 × π × radius
Given the radius is 15.6 cm, substitute into the formula:
Circumference = 2 × π × 15.6 = 31.2π
Now, using π ≈ 3.1416:
Circumference ≈ 31.2 × 3.1416 ≈ 98.0 cm
Thus, the circumference of the circle, to the nearest tenth, is approximately 98.0 cm.

Simplify this solution The Deep Dive
To find the circumference of a circle, you can use the formula C = 2πr, where r is the radius. Here, the radius is 15.6 cm. Plugging that into the formula gives you C = 2 × π × 15.6. Calculating that out, you get approximately 98.0 cm when rounded to the nearest tenth. Now, if you're ever in a situation where you don't have a calculator handy, remember that π is roughly 3.14. So instead of getting lost in complex calculations, you could do a quick estimate using C = 2 × 3.14 × 15.6, which will help you land close to the actual circumference while keeping things simple and stress-free!
