Answer:
Haha proofs are an interesting thing. Usually, nothing is to scale, which is why you can't measure anything. They are pretty annoying, but it helps to know why certain things are the way that they are and develop justification skills for higher level math.
Sorry to discourage you, but you're going to see "Justify" quite a lot in calculus and beyond which is basically a more informal version of a proof
you can never escape it tbh lol
This balloon can travel 450 km every hour. You travel for 2.5 hours, so multiply:
450km/h * 2.5h = 1125km
The answer would be 6, hope this helps
Answer:
44 square inches.
Step-by-step explanation:
radius of the base = 5.5 inches
height of the cylinder = 4 inches
The shape of the vertical cross section of the cylinder through the center of the base would give a rectangle with length of 2r, and its width is the height of the cylinder.
Area of the vertical cross section = height x diameter
diameter of the cylinder = 2r
= 2 x 5.5
= 11 inches
The diameter of the cylinder is 11 inches.
Area of the vertical cross section = 4 x 11
= 44 square inches.
The area of a vertical cross section of the cylinder through the center of the base is 44 square inches.
24.60 - 14.46 = 10.14
10.14 divided by 3 = 3.38
$3.38
hope i helped :)
