Answer:

8 units ^2 are shaded

Step-by-step explanation:

The total area of the square is 4 * 4 = 16

1/2 of the square is shaded so

1/2 * 16 = 8

8 units ^2 are shaded

Answer:

8 units²

Step-by-step explanation:

The area (A) of the shaded part (right triangle ) is calculated as

A = $\frac{1}{2}$ × area of rectangle

= 0,5 × 4 × 4 = 0.5 × 16 = 8 units²

What’s the volume of the cylinder

FrozenT [24]

Answer:

188.496 mm^3 (or 188.495559 mm^3 if you want to be specific)

Step-by-step explanation:

The radius would be the distance from the middle of the circle on top, we are given that the diameter of the circle is 4mm, the radius is half of that so you would get 2 as the radius (or R). H is the height of the cylinder which is 15 mm, so plugging it in (pi * (2^2) * 15) would get you 188.496 mm^3 (rounded of course).

kherson [118]

Answer:

The correct option is B. two oxygen atoms

Step-by-step explanation:

The molecular formula for carbon dioxide is given by :

$CO_2$

Here, the alphabet C stands for Carbon and the alphabet O stands for Oxygen.

And the prefixes of each of these words represents the number of atoms present of the corresponding element in one molecule of carbon dioxide.

So, The prefix of the first word that is C is 1

⇒ One molecule of carbon dioxide contains one atom of Carbon.

The prefix of the second word that is O is 2

⇒ One molecule of carbon dioxide contains 2 atoms of Oxygen.

Therefore, The correct option is B. two oxygen atoms

trapecia [35]

Answer:

A) |-6| + |3|

Step-by-step explanation:

Since the y-coordinates are the same, we need to find the distance between -6 and 3. This would thus be equal to |-6|+|3| making A the correct answer.
