You can find C with pythagorean theorem. And both triangles should be similar (really congruent but it seems like they just decided to not math properly) so you should be able to divide 4/3 then multiply 4 by the outcome. I may be off though bc I have been out of school for 2 months and can't fully remember.

What is the area of the partial circle with a radius of 8 cm?
lina2011 [118]

notice, the circle is missing 1/4, so the area of it is just 3/4 of the whole area of the circle.


\bf \textit{area of a circle}\\\\ A=\pi r^2~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ r=8 \end{cases}\implies A=\pi 8^2\implies A=64\pi \\\\\\ \stackrel{whole}{\cfrac{4}{4}}-\stackrel{one~quarter}{\cfrac{1}{4}}=\cfrac{3}{4}~\hfill \cfrac{3}{4}\cdot 64\pi \implies 48\pi \implies \stackrel{\pi =3.14}{150.72} \\\\\\ ~\hspace{34em}

Who knows what 5 to the power of 2 i
Alexxandr [17]
If you mean 5^2 and not 5^2i then
5^2 just means 5 times itself,twice or 5 times 5 or 25


if you meant 5^2i
i=√-1
so law of exponents says a^(xz)=(a^x)^z so
5^2i=(5^2)^i or (25)^i
the answer (if you wanted 5^2i) is 25^i


IF YOU MEANT 5^2 then the answer is 25

Sharon travels 15 miles west and then 8 miles south. How far is she from her starting point
ZanzabumX [31]

Answer:

As soon as the car travels south you would take 5 miles off the 8 south which would make it 3 miles but you would have to add an extra 6 as it also travelled west so the car would have to travel east to arrive at the initial starting point.
