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;
[tex]d=2r[/tex]
Substituting r = 7, we get;
[tex]d=2(7)[/tex]
[tex]d=14 \ mm[/tex]
Thus, the diameter of the coin is 14 mm.
Circumference of the coin:
The circumference of the coin can be determined using the formula,
[tex]C=\pi d[/tex]
Substituting [tex]\pi=3.14[/tex] and [tex]d=14[/tex], we get;
[tex]C=(3.14)(14)[/tex]
[tex]C=43.96 \ mm[/tex]
Thus, the approximate value of the circumference of the coin is 43.96 mm
Answer:
The satang coin from Thailand has a radius of about 7 mm.
We need to determine the diameter and circumference of the coin.
