The radius of a circular disc is 0.25 meter. What is the approximate circumference?

A. 0.0625 meter
B. 0.19625 meter
C. 0.785 meter
D. 1.57 meters

Answer :

Final answer:

The circumference of a circle with a radius of 0.25 meters is approximately 1.57 meters., the right answer is D.

Explanation:

You're asking about the circumference of a circle with a radius of 0.25 meters. The formula to calculate the circumference of a circle is

C = 2πr

, where C is the circumference, π is a constant approximately equal to 3.14, and r is the radius. Substituting the given radius into the circumference formula yields C = 2 * 3.14 * 0.25 = 1.57 meters. Thus, the approximate circumference of the circle is 1.57 meters, making

D

the correct option.
