Answer:

It could be 2:5 or 6pi:15pi

Step-by-step explanation:

If you write the ratio of the surface area as a fraction, you would get $\frac{20\pi *yd^{2} }{125\pi *yd^{2} }$ . Simplifying it would leave $\frac{4}{25}$ . But this is NOT the answer because that is the ratio of the surface area. You have to square root it to find the scale factor. The square root is $\frac{2}{5}$ . The answers would be 2:5 and 6pi:15pi.

You have to do 3 2
--- + ---. You have to do 3 + 2 which is 5, and leave the
8 8 denominators the same, so the answer is 5/8.

If you raise 4 to the 214th power, what is the units digit of the result

Len [333]

$\begin{array}{lrlll}
4^1&\boxed{4}\\
4^2&1\boxed{6}\\
4^3&6\boxed{4}\\
4^4&25\boxed{6}\\
4^5&102\boxed{4}\\
4^6&409\boxed{6}
\end{array}\impliedby \textit{see the pattern for 4?}$

notice, it goes 4,6 then 4, 6 again, and so on and so on
based on whatever exponent it may have

now, you're being asked, what 214 will give? 4 or 6?
