Calculate the circumference of a circle with a diameter of 10.

The correct approach to calculating the circumference of a circle involves using the formula that relates the circumference to the diameter. The formula states that the circumference equals π multiplied by the diameter.

In this case, the diameter is given as 10. Therefore, using the formula, we can express the circumference as:

Circumference = π × diameter = π × 10.

The correct answer should reflect this understanding. While the chosen response identifies the relationship correctly, it's important to note that the circumference of the circle can also be directly computed from the given diameter. Thus, understanding the properties of circles and being able to apply the appropriate formulas is crucial for solving such problems accurately.

Taking the actual diameter of 10 into consideration, it is also clear that if one calculates directly based on the diameter, they would arrive at the circumference being 10π. This clarity aids in solidifying the concept of circumference in the geometry of circles.
