Answer:
631ml
Step-by-step explanation:
In order to find how much water is in the snow globe, we need to find it's volume. Volume formula for the sphere is πr²
π(3.5)² ≈ 38.5in³
To know how much water is in the sphere, we can transform 38.5in³ into milliliters.
1 cubic inch is 16,3871 ml
38.5 x 16,3871 ≈ 631ml

Step-by-step explanation:
Answer:
The radius of a hexagon is called the apothem, which in this case is 15.
We need to know the side length which is found by the equation:
side length = apothem * 2 * (tan (180 / #sides))
side length = apothem * 2 * (tan (180 / 6))
side length = 15 * 2 * (tan (30 degrees))
side length = 30 * .57735
side length = 17.3205
We need the perimeter of the hexagon which equals the side length times six.
perimeter = 6 * 17.3205 = 103.923

Step-by-step explanation:
The area of the classroom is 8,671 in squared. you get this by multiplying base x height x width. You plug the same formula into the dollars he mentions and get 0.06890922 in squared. Than you divide the classroom dimensions by the dollar dimentions. that's 8,671 ÷ 0.06890922 = 125,832.21809795. rounding that to one decimal place, it would take $125,832.2 to fill up the classroom. (I might have gotten this wrong but I think this is the answer)
