I need some help finding the volume of a sphere with a diameter of 18.6cm. The website says the answer I got from my calculator was wrong! Help would be greatly appreciated!

Answers

Answer:

Volume, V = 3367.6 cm³

Step-by-step explanation:

Given the following data;

Diameter = 18.6 cm

Radius = diameter/2 = 18.6/2 = 9.3 cm

Pie, π = 3.14

To find the volume of the sphere;

Mathematically, the volume of a sphere is given by the formula;

[tex] Volume \; of \; a \; sphere = \frac {4}{3} \pi r^{3} [/tex]

Where;

r is the radius of the sphere.

Substituting into the formula, we have;

[tex] V = \frac {4}{3} * 3.14 * 9.3^{3} [/tex]

[tex] V = 4.186666667 * 804.357 [/tex]

Volume, V = 3367.6 cm³

1. Predict the height ( in cm) of boy
who is 30 months old.
2. Predict the age of a boy who is approximately 115 cm tall.
Use the linear model equation y=0.58x+72.27.

Answers

Answer:

Step-by-step explanation:

It'd be wise to say what is represented by each x and y.  I will assume that x represents the age of the child in months and y the height in cm.

Then, if the height is 115 cm, 115 cm = 0.58x + 72.27.  Must solve this for x:

     115 cm - 72.27 cm

x = ---------------------------- = 73.7 cm (about 29 inches, which is reasonable)

                 0.58

If the child is 30 months old, x = 30 and y (the height) is

0.58(30) + 72.27 cm = 89.7 cm (about 35.3 cm, also reasonable)

Una caja de carton se ha disenado para qu contenga 184cm cubicos. Si su altura es de 10cm, cual es el area de la base?

Answers

Answer:

18.4 cm²

Step-by-step explanation:

Una caja de carton se ha disenado para qu contenga 184cm cubicos. Si su altura es de 10cm, cual es el area de la base?

Volumen = Área de la base × Altura

Área de la base = Volumen / Altura

= 184 cm³ / 10 cm

Área de la base = 18.4 cm²

Por lo tanto, el área de la base es de 18.4 cm².

What is the value of n if 6n + 7 = 2n + 5? Memories of a MemoryHave you ever witnessed something amazing, shocking or surprising and found when describing the event that your story seems to change the more you tell it? Have you ever experienced a time when you couldn't really describe something you saw in a way that others could understand? If so, you may understand why some experts think eyewitness testimony is unreliable as evidence in scientific inquiries and trials. New insights into human memory suggest human memories are really a mixture of many non-factual things.First, memory is vague. Imagine your room at home or a classroom you see every day. Most likely, you could describe the room very generally. You could name the color of the walls, the floors, the decorations. But the image you describe will never be as specific or detailed as if you were looking at the actual room. Memory tends to save a blurry image of what we have seen rather than specific details. So when a witness tries to identify someone, her brain may recall that the person was tall, but not be able to say how tall when faced with several tall people. There are lots of different kinds of "tall."Second, memory uses general knowledge to fill in gaps. Our brains reconstruct events and scenes when we remember something. To do this, our brains use other memories and other stories when there are gaps. For example, one day at a library you go to quite frequently, you witness an argument between a library patron and one of the librarians. Later, when telling a friend about the event, your brain may remember a familiar librarian behind the desk rather than the actual participant simply because it is recreating a familiar scene. In effect, your brain is combining memories to help you tell the story.Third, your memory changes over time. It also changes the more you retell the story. Documented cases have shown eyewitnesses adding detail to testimony that could not have been known at the time of the event. Research has also shown that the more a witness's account is told, the less accurate it is. You may have noticed this yourself. The next time you are retelling a story, notice what you add, or what your brain wants to add, to the account. You may also notice that you drop certain details from previous tellings of the story.With individual memories all jumbled up with each other, it is hard to believe we ever know anything to be true. Did you really break your mother's favorite vase when you were three? Was that really your father throwing rocks into the river with you when you were seven? The human brain may be quite remarkable indeed. When it comes to memory, however, we may want to start carrying video cameras if we want to record the true picture.Which line from the text best explains the main problem with recalling details of a scene or room?
