Step-by-step explanation:

Figure RSTU and Figure XWZY are the same meaning it has the same side lengths and angles. Also, if you reflect the shape the angle will be on the same side. The side lengths are not shown on Figure XWZY but they are the same.

Answer:

3) 16π cm²

4) 240.625 cm²

Step-by-step explanation:

<em>3. For this problem I'm going to use the formula Area = π × r²</em>

<em>To start off, I'm going to input our value of radius which is 4cm.</em>

π × 4²

<em>Finally, I'm going to square our value "4"</em>

16π cm²

<em>(I'm going to "leave my answer in terms of π" as the problem states but if you need the complete answer it would be </em>about 50.24 cm²

<em>4. For this problem I'm going to use the formula Area = π × (d/2)²</em>

<em>To begin, I will divide our diameter by 2 to find the radius.</em>

17.5/2 = 8.75

<em>Next, we are going to square our now, radius.</em>

8.75² = 76.5625

<em>Now, we have to multiply our squared radius by π (in this problem it states to use 22/7, so that's what we'll do :)</em>

76.5625 × 22/7 = 240.625 cm²

<em>So! This is our final answer!</em>

<em />

Hope this Helps! :)

Evaluate the expression. StartFraction 9 factorial Over 3 factorial EndFraction 3 6 60,480 362,874
REY [17]

Answer:

60,480 is the correct answer.

Step-by-step explanation:

First of all, let us have a look at the <em>formula of factorial of a number 'n'</em>:

n! = n \times (n-1) \times (n-2) \times ...... \times 1

i.e. multiply n with (n-1) then by (n-2) upto 1.

<em>Keep on subtracting 1 from the number and keep on multiplying until we reach to 1.</em>

<em></em>

So, 9! can be written as: 9 \times 8 \times 7 \times ...... \times 1

Similarly 3! can be written as: 3 \times 2 \times 1

Re-writing 9 ! :

9 \times 8 \times 7 \times ...... 3 \times 2 \times 1\\\Rightarrow 9 \times 8 \times 7 \times ...... 3 !

Now, the expression to be evaluated:

\dfrac{9!}{3!} = \dfrac{9 \times 8 \times 7 \times ..... \times 3!}{3!}\\\Rightarrow 9 \times 8 \times 7 \times 6 \times 5 \times 4\\\Rightarrow 60480
