Question

What is the circumference of a circular disc with a diameter of 10 centimeters? (Round your answer to the nearest tenth.)

Answer 1

To determine what the circumference is simply take the value of the diameter and multiply it to the value of Pi or 3.141....

C = Pi • d
C = (3.14)(10 cm)
C = 31.41 cm or 31.4 cm, rounded to the nearest tenth.

Answer 2

The circumference of the circle is 31.4 cm

What is Circumference of circle?

The circumference of a circle refers to the measure of its boundary. If we open a circle and measure the boundary just like we measure a straight line, we get the circumference of the circle in terms of units of length like centimeters, meters, or kilometers.

Now let us learn about the elements that make up circumference. These are the three most important elements of a circle.

• Center: The center of the circle is a point that is at a fixed distance from any other point from the circumference.
• Diameter: The diameter is the distance across the circle through the center, it is a line that meets the circumference at both ends and it needs to pass through the center.
• Radius: The radius of a circle is the distance from the center of a circle to any point on the circumference of the circle.

The formula for the circumference of a circle is expressed using the radius 'r' of the circle and the value of 'pi'. It is expressed as, Circumference of a circle formula = 2πr.

Given:

diameter= 10 cm

So,

Circumference of circle is = πd

=3.14* 10

=31.4 cm
