What is the question to this explanation?
I hope this helps you
area formula=pi.r^2
1) Area=3,14. (3,5)^2
Area=38,465
Area nearest 38,5
2) Circumference=2pi.r
Circumference=2.3,14.3,5
Circumference=21,98
Circumference nearest 22
The square root of 29 is 5.3851
Compare the first number. In this case, both are five, so move on to the next number.
7 is greater than 3, so the answer would be 5.7145 > The square root of 29.
Answer:
C is correct

do you know why? haha
Answer:
Step-by-step explanation:
There are 6 solutions or zeros here because, according to the Fundamental Theorem of Algebra, the degree of the polynomial dictates how many zeros there are in the polynomial. If we had a 3rd degree polynomial, we would expect to find 3 zeros; if we had a 5th degree polynomial, we would have 5 zeros, etc. The easiest way to factor this is to do it initially by grouping:
then
then

We will factor each set of parenthesis now to get all the zeros. For the first set of parenthesis:
so
so

But since we can't have a negative under the square root, we have to offset it by using the imaginary number i. i-squared = -1, so
x = ±i√5
Those are the first 2 zeros out of 6. Now for the second set of parenthesis:
4x⁴ - 25 = 0. That is the difference between perfect squares, and that factors to this:
(2x² + 5)(2x² - 5)
The first set of parenthesis there:
2x² + 5 = 0 so
2x² = -5 so
x² = -5/2 so
x = ±
Those are the next 2 zeros. We found 4 so far, now we will find the last 2 in the second set of parenthesis above:
so
so
x = ±
In summary, the 6 zeros are as follows:
x =
