Answer: The distance around a semicircle is called its semicircumference, and it is equal to half the circumference of a full circle with the same radius.
Therefore, to find the semicircumference of the given semicircle, we first need to find the circumference of the full circle with radius 6 cm (since the diameter of the semicircle is given as 12 cm).
The formula for the circumference of a circle is C = 2πr, where r is the radius of the circle.
So, for the full circle with radius 6 cm, the circumference would be:
C = 2π(6) = 12π
Therefore, the semicircumference of the given semicircle is half this value:
Semicircumference = 1/2(12π) = 6π
Using the value of π as 3.14, we can approximate the semicircumference to:
Semicircumference ≈ 6(3.14) = 18.84 cm
Therefore, the distance around the given semicircle is approximately 18.84 cm.
