Question

applying circumference
this shape is made up of one half - circle attached to an equilateral triangle with side lengths 17
inches. you can use 3.14 as an approximation for π.
the circumference of the whole circle is about 53.38 inches.
the distance around the half - circle is about

Explanation:

Step1: Recall circumference formula for half - circle

The formula for the circumference of a full - circle is $C = 2\pi r$, and for a half - circle, it is $C_{semicircle}=\pi r$. The diameter of the half - circle is 17 inches, so the radius $r=\frac{17}{2}$ inches.

Step2: Calculate the circumference of the half - circle

Using $\pi\approx3.14$, we have $C_{semicircle}=3.14\times\frac{17}{2}=3.14\times8.5 = 26.69$ inches.

Answer:

26.69
