Question

In circle a line segment AC is 6 cm using this information what is the best estimate of the circumference of circle a?

Answer 1

With a radius of 6 cm, the best estimate of the circumference (C) of circle A, using the formula
`\(C = 2\pi r\)`, is approximately 37.68 cm.

The circumference C of a circle is given by the formula
`\(C = 2\pi r\)`, where r is the radius. In this case, the radius r is 6 cm.

`\[ C = 2 \pi * 6 \]`

Using an approximate value for
`\(\pi\)` of 3.14:

`\[ C \approx 2 * 3.14 * 6 \]\[ C \approx 37.68 \, \text{cm} \]`

So, the best estimate of the circumference of circle A is approximately 37.68 cm.

In circle A, where the radius (line segment AC) is 6 cm, the circumference (C) is estimated using the formula
`\(C = 2\pi r\)`. With a radius of 6 cm, the calculation yields an approximate circumference of 37.68 cm, assuming π is approximately 3.14. This represents the total distance around the circle, providing a measure of its boundary length.
