Question

this shape is made up of one half-circle attached to an equilateral triangle with side lengths 14 inches. you can use 3.14 as an approximation for $pi$.what is the approximate perimeter of the entire shape? solve on paper, and enter your answer on zearn. you can use your zearn calculator to help you solve.the perimeter of the shape is about $square$ inches

Explanation:

Step1: Find semicircle circumference

The diameter of the semicircle is equal to the side length of the triangle, 14 inches. The formula for the circumference of a full circle is $C=\pi d$, so the semicircle length is $\frac{1}{2} \times \pi \times d$.
$\frac{1}{2} \times 3.14 \times 14 = 21.98$ inches

Step2: Sum triangle outer sides

The shape includes 2 sides of the equilateral triangle, each 14 inches.
$14 + 14 = 28$ inches

Step3: Total perimeter calculation

Add the semicircle length and the triangle side lengths.
$21.98 + 28 = 49.98$ inches

Answer:

49.98 inches
