\bf \textit{surface area of a sphere}\\\\
SA=4\pi r^2~~
\begin{cases}
r=radius\\
------\\
SA=2122.64
\end{cases}\implies 2122.64=4\pi r^2
\\\\\\
\cfrac{2122.64}{4\pi }=r^2\implies \cfrac{530.66}{\pi }=r^2\implies \sqrt{\cfrac{530.66}{\pi }}=r

C. Assume someone has an average balance account with a bank that costs $35 a month but earns
Elodia [21]

Answer:

<em>The total interest earned after subtracting the monthly $35 </em>

<em>service fee = $975 - $35 = $940</em>

Step-by-step explanation:

Bank fee cost per month = $35

Interest rate per month = 1%

The total amount in the account until the 15th = $100,000

The total amount in the account from the 15th to the 30th = $95,000

Interest Earned?

<em>Interest earned for first 15 days:</em>

                               = $100,000 times 1%/2

                               = $100,000 times 0.001/2

                               = $500

<em>Interest earned from 15th to the 30th:</em>

<em>                                  </em>= $95,000 times 1%/2

                                 = $95,000 times 0.001/2

                                 = $475

Interest earned for <em>first 15 days + Interest earned from 15th </em>

<em>to the 30th =  </em>$500 + $475 = $975

So, the total interest earned after subtracting the monthly $35

service fee = $975 - $35 = $940

The mean radius of Earth is 6,371.0 kilometres and the mean radius of Earth’s Moon is 1,737.5 kilometres.
OLEGan [10]

Answer: 29,113.2 km

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Circumference = 2 x π x radius

Replacing with the values given:

Earth's mean circumference = 2 π 6,371.0 = 40,030.2 km

Earth's moon mean circumference = 2 π 1,737,5= 10,917 km

Now, we have to subtract Earth's moon mean circumference to Earth's mean circumference:

40,030.2- 10,917 =29,113.2 km

Feel free to ask for more if needed or if you did not understand something.
