Question

A half circle is joined to an equilateral triangle with side lengths of 12 units. what is the perimeter of the resulting shape?

Answer 1

The perimeter of the half circle is pi * r. Since the circle is linked to the equilateral triangle, then the diameter of the circle is 12. Therefore r = 6.Then, the perimeter of the resulting figure is:P = 6 * pi + 12 +12 = 42.85 Units.

Answer 2

Answer:

Since the circle is linked to the equilateral triangle, then the diameter of the circle is 12. Therefore r = 6.Then, the perimeter of the resulting figure is:P = 6 * pi + 12 +12 = 42.85 Units.
