Help Por FavOr :)What is the approximate volume of a cylinder with a radius of 3 ft and a height of 4 ft?

Use 3.14 to approximate pi.
Express your answer in hundredths.

_____ft3

Answers

Answer 1
Answer: find the circumference of the base face:
(3*2) \pi
that is 18.84
then you multiply that by 4
which is 75.36
the answer is 75.36 ft^3
Answer 2
Answer: The volume of a cylinder is the area of the base (π r^2) times the height (h). So it's V = π r^2 h. HOPE I HELPED

42/4 as a improper fraction

Answers

To figure this out, we need to look for how many times 4 can go into 42.

4*10=40

Later, we have a remainder of 2 because 42-40=2

We write 10 as the whole number and 2 on the numerator.

10 2/4 = 10 1/2

Final answer: 10 1/2 is the mixed number, but the improper fraction simplified is 21/2 

Improper fraction: 21/2
Mixed number: 10 1/2
**CORRECTION** 21/2 because when you simplify it (dividing the top and the bottom by 2) you get 21/2. My first asnwer was a mixed number

PLEASE ANSWER ASAP! VERY IMPORTANT! MORE POINTS GIVEN!William said that when you multiply three positive and negative decimals, the answer changes depending on where you place the parentheses. Use these numbers to answer the questions: –2.4, –0.63, 1.8, –3.42

Write a rule describing the results when one multiplies three positive and negative decimals and
changes the order of multiplication using parentheses.

Answers

so as seen in the previous problem and using the associative propery of multiplication which is a(bc)=(ab)c we can conclude that the order doesn't matter so then we find the part with the positives and negatives
so we will see what happens when we multipliy positives and negatives
so we remember these rules
(+)=positive
(-)=negative
(+) times (+)=(+)
(-) times (-)=(+)
(+) times (-)=(-)
(-) times (+)=(-)

basically group in pairs and write the signs down to conclude proper signs ex.
-2 times 2 times 4 times -3 would be (-2 times +2) times (+4 times -3) or (- times +) times (+ times -)=(-) times (-) =+
basically just do this over and over again untill you get 1 sign



basically the rule is if you multiply 2 pairs of signs, if the signs are the same, then the result is positive
if the signs are different, then the result is negative

(+) times (+)=(+)
(-) times (-)=(+)
(+) times (-)=(-)
(-) times (+)=(-)

Which special version of the Pythagorean Theorem can you use to find the length of any square's diagonal, d, using only the length of its side, s?

Answers

Using the Pythagorean Theorem, the length of a square diagonal, in function of it's sides s, is given by:

d = s√(2)

The Pythagorean Theorem relates the length of the legs l_1 and l_2 of a right triangle with the length of the hypotenuse h, according to the following equation:

h^2 = l_1^2 + l_2^2

In a square, as given in the figure below, the legs are the sides s, of equal measure, while the hypotenuse is the diagonal d, thus:

d^2 = s^2 + s^2

d^2 = 2s^2

d = √(2s^2)

d = s√(2)

A similar problem is given at brainly.com/question/21691542
the square's diagonal is the triangle's hypotenuse.

the original Pythagorean theorem is  a^(2) + b^(2) = c^(2)   where a and b are the two sides and c is the hypotenuse.

that means the Pythagorean theorem for this question is:

s^(2) + s^(2) = d^(2)  or 2( s^(2) )= d^(2)
