The circumference of a circle is pi(d). Since the bottom half of the shape is a semicircle, we know the radius is 9 and the diameter 18. So, the circumference (aka perimeter) of that semicircle would be (3.14x18)/2. Then add 5+5+12in.

Answer:

50.26 units.

Step-by-step explanation:

Perimeter of the given picture = perimeter of trapezoid with 3 sides + perimeter of semicircle.

Perimeter of trapezoid = 12 + 5 + 5

= 17 + 5

= 22

Perimeter of semicircle = π r

= π × 9

= 3.19 × 9

= 28.26

Now perimeter of the figure = 28.26 + 22

= 50.26 units.

If the amount of water used is constant regardless of the amount of sugar, the appropriate graph would be the second graph. the graph with the straight line
