water should Jenny use?

3 cups of water

Step-by-step explanation:

it she is making the humming bird stuff and 1/4 is supposed to be sugar and she uses a cup of sugar then the other stuff is supposed to be water so 3 cups of water

5.8 cm

Step-by-step explanation:

Let's call the length of the chord 'c'.

To find the length of the chord, we can use the Pythagoras' theorem in the triangle ABC as shown in the image attached.

r^2 = (c/2)^2 + 0.8^2

9 = c^2/4 + 0.64

c^2/4 = 8.36

c^2 = 33.44

c = 5.78 cm

Rounding to nearest tenth, we have that the length of the chord is c = 5.8 cm.
