Find the circumference and the area of a circle with diameter 8 pie 3.14

Mathematics
1 answer:
Nata [24]3 years ago
6 0

Answer:

The answer is c = 25.13 a =50.27

The answer to this question is extremely simple. Think of it this way. When you have 2 apples and you eat one how many do you have left? Well we can use the Pythagorean theorem, a^2 + b^2 = c^2, so 2^2 -1^2 = ?. Well how do you find exponents?

Good. What is the Pythagorean theorem? The Pythagorean theorem consists of a formula a^2+b^2=c^2 which is used to figure out the value of (mostly) the hypotenuse in a right triangle. The a and b are the 2 "non-hypotenuse" sides of the triangle (Opposite and Adjacent). Very simple. So you would have one apple remaining.

tensa zangetsu [6.8K]

Answer:

4K

Step-by-step explanation:

\frac{J}{24} = K ( multiply both sides by 24 to clear the fraction )

J = 24K ( divide both sides by 6 )

\frac{J}{6} = 4K

If $x$ is the average of $13$, $-16$, and $6$ and if $y$ is the cube root of $8$, find $x^2 + y^3$. Please Help
Alekssandra [29.7K]

Answer:

If we have a set of N elements:

{x₁, x₂, ..., xₙ}

The mean value (also called the average value) Is calculated as:

Average = (x₁ + x₂ + ... + xₙ)/n

So if x is the average of 13, -16 and 6 ( a total of 3 values)

x will be equal to:

x = (13 + (-16) + 6)/3 = (19 - 16)/3 = 3/3 = 1

x = 1

And we know that:

y = ∛8

Remember that:

2*2 = 4

and

4*2 = 8

then

2*2*2 = 2^3 = 8

then ∛8 = 2.

So we have:

y = ∛8 = 2

Now we can replace these values in the equation:

x^2 + y^3

replacing:

x = 1

y = 2

we get:

1^2 + 2^3 = 1 + 8 = 9
