the approximate value of the circumference is

mm

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;

Substituting r = 7, we get;

Thus, the diameter of the coin is 14 mm.

Circumference of the coin:

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

Substituting and , we get;

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

because parallelagram have all 4 angels the same size dependeing and a rectangle and square are oth parallelogram

you have to find the same variables -3n - 5n so this would be -3n +(-5n) which equals -9n
