You need to fill a cylindrical glass with water. the glass is 6 inches tall and 2

Mathematics
1 answer:
Maurinko [17]2 years ago
4 0
Answer:
volume = pi x r^2 ×h
where r is radius and h is height.
h= 6 in
r= 1
V=(22/7)×1^2 ×6
V=18.857in^3
Step-by-step explanation: Since the glass cup is cylindrical in shape, we use the formula for find volume of a cylinder iff the glass cup is to be filled full.
The volume of water will be equal to the volume of the cup. Across the widest point means diameter, hence half diameter gives radius.

What is an equation of the line in point-slope form? How can the point-slope form be written in function notation?
harina [27]
The equation of a line in point slope form = y - y_1 = m(x - x_1)

To put y - y_1 = m(x - x_1) into function notation, we need to get y by its self.
Lets say we had a point (2,2) and a slope of 3. Ok, now that we have our point and slope, lets turn point slope form into  function notation.

y - y_1 = m(x - x_1)
y - 2 = 3(x - 2)
y - 2 = 3x - 6
y = 3x - 6 + 2
y = 3x - 8
Change the y to f(x)
f(x) = 3x - 8      <-----Function notation.

3a+3b,for a=2 and b=4
il63 [147K]
3a + 3b, for a=2 and b=4 ... The first thing you'd do would be to plug the numbers in -

3 x 2 + 3 x 4 

Then multiply them -

6 + 12 

Then add - 

18.

So your answer should be 18.

Help! This is due today and I'm stuck on this problem.
Varvara68 [4.7K]

Answer:

280.6 m^2

Step-by-step explanation:

<u>find the length of each side:</u>

you're only given h = 9 m

the formula for h is  h=\frac{\sqrt{3} }{2} *a, where a is a side length of the hexagon

plug h in:

9=\frac{\sqrt{3}}{2}*a\\\\a=9*\frac{2}{\sqrt{3}}\\\\

a ≈ 10.392 m

<u>now find the area of a triangle:</u>

1/2 (10.392)(9) = 46.764 m^2

multiply that by 6 and you get 280.584 ≈ 280.6 m^2

you can also use the regular hexagon area formula instead of finding the individual area and multiplying by 6: \frac{3\sqrt{3} }{2} *a^2
