Answer:

V ≈ 7850

Step-by-step explanation:

V= πr^2h is the formula

so V = 3.14 * 10^2 * 25

V = 3.14 * 2500 = 7850

depending on what decimal you use for pi, your answer will differ

Prove that using: X ∩ (Y ∪ Z ) =(X∩Y) ∪ (Y ∩ Z )
sertanlavr [38]

There should be a typo in the question: the correct formula would be

X\cap(Y\cup Z)=(X\cap Y)\cup (X\cap Z)

Let's compute X\cap (Y\cup Z) first. We have

(Y\cup Z)=\{1, 4, 5, 6, 7, 8, 9\}

If we intersect this set with X, we have

X\cap (Y\cup Z) = \{5, 8, 9\}

So, that would be the left hand side. For the right hand side, we have

X\cap Y = \{8\},\quad X\cap Z = \{5,9\}

And their union is again \{5,8,9\}

How many 3/4s are in 3 2/4
MArishka [77]

Answer:

the answer is 3

Step-by-step explanation:

First change the whole number (3) to quaters or fraction

3x \frac{4}{4} = \frac{12}{4}

Now, add

\frac{2}{4} + \frac{12}{4} = \frac{14}{4}   Since, we have the same common denominator

now divide

14÷4 =3.5 = 3\frac{2}{4}

Therefore, there are 3 of 3/4 with a remainder of  \frac{2}{4} in 3 \frac{2}{4}.
