Answer:

30 cm

Step-by-step explanation:

The perimeter of a circle is 2 $\pi$ r where r is the radius. Therefore, the perimeter of the semicircle would be $\pi$ r + the diameter (because there is only half of the circle's arc). Using the value $\pi$ = 3 and d (diameter) = 12, the area of the circle would be 3(6) + 12 which is 18 + 12 which is 30 cm.

Hope this helps :)

Answer:

20 ounces

Step-by-step explanation:

For this type of problem it is best to work backwards.

If David has 18, and Charlie gave him 1/2, then Charlie has 36 because 18x2=36. Barbara has 60, because 36/3= 12 and 5x12=60. Then, Amanda has 80 because 60/3=20 and 20x4= 80. But, we need to subtract 60 because the problem asks how many ounces of water does Amanda <em>still</em> have. So, 80- 60(The amount of water she gave to Barbara)=20.
