A mirror that is 4 ft wide is to be centered on a wall that is 16 ft long. How far from each end of the wall should the mirror’s ends be placed?

==============================================================

Explanation:

The mirror is 4 ft wide and we have 16 ft of wall to work with. That leaves 16-4 = 12 ft of buffer room or empty space. Splitting that empty space into two equal regions (left and right) means 12/2 = 6 ft is the width of the empty space on either side.

Therefore, each end of the mirror should be 6 ft from either end of the wall. Refer to the diagram below. Note how all of the values in the second row add to 16.

the correct answer is semicircle

step-by-step explanation:

the answer is semicircle because the shorter arc joining two points on the circumference of a circle is known as the minor arc, the larger arc is called the major arc, and a semicircle is a half circle, formed by cutting a whole circle along a diameter line.
