Help please!!
find the circumference of a circle, diameter measures 10 cm​

Answer 1

31.42 cm

Explanation:

First, to find the circumference when given the diameter, the equation is: pi times the diameter.

Then, since the diameter is 10 cm, you just multiply 10 times 3.14 (pi)

Finally, 10 times 3.14 is 31.42, and that is the circles circumference.

Answer 2

The circumference of this circle would be roughly around 31.42 centimeters.

Explanation:

To find the circumference of a circle, you can use the formula

2πr where r is the radius.

Since we know the diameter, e can just divide it by 2 to get the radius.

10/2=

So, we can replace the equation.

2π5=

(2·5)·π=

10π ≈ 31.42
