Please answer this correctly without making mistakes

Answer:

263.76

Step-by-step explanation:

Assuming the shaded area is the yellow area all we must do is find the area of the small circle and subtract it from the larger circle.

To do this we can use the area of a circle equation:

$A=\pi r^2$

first we need to find the radius of the large circle which is simply 4+6= 10

so the area would be:

$A=\pi 10^2\\A=100\pi$

then we find the area of the small circle is

$A=4^2\pi \\A=16 pi$

next we evaluate:

$100\pi -16\pi =84\pi$

Then replace pi with 3.14:

84 · 3.14 = 263.76

And you have your answer!

Hope this helps!

2^n-5×5^n-4=5

Papessa [141]

$\huge{\fbox{\sf{n=5 }}}$

Step 1:

$⇒ {2}^{n - 5} \times {5}^{n - 4} = 5$

Step 2:

$⇒{2}^{n - 5} \times {5}^{n - 4} = {5}^{1} \times {2}^{0}$

On comparing values we get:

Taking:

${2}^{n - 5} = {2}^{0}$

n-5=0

n=5✓

Taking:

${5}^{n - 4} = {5}^{1}$

n-4=1

n=5✓

Answer: $19,267.0$

Step-by-step explanation:

1. You have the following information given in the problem above:

$(1*10,000)+(3*100)+(5*10)+(9*101)+(8*1001)$

2. To solve this exercise, first you must multiply the number that ar inside the parentheses and then you must add all of them, as you can see below:

$10,000+300+50+909+8008=19,267$

3. Rewriting is as a decimal, you have that the answer is:

$19,267.0$
