the approximate value of the circumference is

mm

Answer 1

The satang coin from Thailand has a radius of about 7 mm.

We need to determine the diameter and circumference of the coin.

Explanation:

Answer 2

Given:

The satang coin from Thailand has a radius of about 7 mm.

We need to determine the diameter and circumference of the coin.

Diameter of the coin:

The diameter of the coin can be determined by multiply the radius by 2.

Thus, we have;

`d=2r`

Substituting r = 7, we get;

`d=2(7)`

`d=14 \ mm`

Thus, the diameter of the coin is 14 mm.

Circumference of the coin:

The circumference of the coin can be determined using the formula,

`C=\pi d`

Substituting
`\pi=3.14` and
`d=14`, we get;

`C=(3.14)(14)`

`C=43.96 \ mm`

Thus, the approximate value of the circumference of the coin is 43.96 mm
