Question
Find the perimeter of the figure to the nearest hundredth. pls help

Answer 1

50.26 in

Explanation:

First you need the circumference of half of a circle.

Circumference = diameter x pi. The radius is 9, so the diameter is 18. 18 * 3.14 = 56.52. But you need half of that, so 56.52 / 2 = 28.26

Then add the other 3 sides

28.26 + 5 + 12 + 5 = 50.26
