No question but can you help me with Finding PI lol I don’t really get it. I will mark brainliest 60 points 30 for each person t
Brut [27]

Answer:

Make sure you are using a perfect circle. This method won't work with ellipses, ovals or anything but a real circle. A circle is defined as all the points on a plane that are an equal distance from a single center point. The lids of jars are good household objects to use for this exercise.You should be able to calculate pi roughly because in order to get exact results of pi, you will need to ...

Measure the circumference of a circle as accurately as you can. The circumference is the length that goes around the entire edge of the circle. Since the circumference is round, it can be difficult to measure (that's why pi is so important). Lay a string over the circle as closely as you can. Mark the string off where it circles back around, and then measure the string length with a ruler.

Measure the diameter of the circle. The diameter runs from one side of the circle to the other through the circle's center point.

Use the formula. The circumference of a circle is found with the formula C= π*d = 2*π*r. Thus pi equals a circle's circumference divided by its diameter. Plug your numbers into a calculator: the result should be roughly 3.14.[3] X Research source

Repeat this process with several different circles, and then average the results.

F(x) = x^2 + 7x-4 find the second derivative
Ulleksa [173]

We know that f(x) = 7x + 8. So, take the derivative of this function with respect to x.

This gives

f'(x) = 7

Now, you probably realized that the x value disappeared. This means that no matter what value of x you use, the derivative of this function is always going to be 7, even at x = 5. That is, the rate of change of this function is always going to be a rate of 7.
