Question

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

Answer 1

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
