How do you find the circumference of a circle worksheet?

Apply the formula C = πd, where C is the circumference of a circle and d is the diameter, to work out the problems here. Using π ≈ 3.14 is the key. Study the circles depicted with their diameters(d) and multiply the d < 100 units by 3.14 to obtain the circumference. Do round your answer to the nearest tenth.

Is circle a circumference?

In geometry, the circumference (from Latin circumferens, meaning “carrying around”) is the perimeter of a circle or ellipse. That is, the circumference would be the arc length of the circle, as if it were opened up and straightened out to a line segment.

How do you work out the circumference?

Circumference of a circle

1. For any circle with diameter, , the circumference, , is found by using the formula.
2. C = π d.
3. = π × 8.
4. = 25.13 c m.
5. Remember that, for any circle, the diameter is twice the radius, or d = 2 r .
6. = 2 × 3.
7. = 6 c m.
8. C = π d.

How do you use pi formula?

Use the formula. The circumference of a circle is found with the formula C= π*d = 2*π*r. Thus, pi equals a circle’s circumference divided by its diameter. Plug your numbers into a calculator: the result should be roughly 3.14.
