Answer:

V candle ≈ 196.9 cm³

Step-by-step explanation:

Volume of cone = ( π·r²·h)/3

V candle = V big cone -V small cone

V candle = [ π·4²·(8+5) - π·2²·5]/3

V candle = ( π·16·13 - π·4·5)/3

V candle = (π·16·13 - π·4·5)/3

V candle = π·(208 - 20)/3

V candle = π·188/3

V candle = 196.8731396

V candle ≈ 196.9 cm³

Question: Simplify $\frac{\sqrt{8x^2}}{\sqrt{2x}}$ .

First off, you never want square roots on the bottom of a fraction, so let's multiply both sides by $\sqrt{2x}$ to get rid of it. All we have to do from there is simplify!

$\frac{\sqrt{8x^2}}{\sqrt{2x}}*\frac{\sqrt{2x}}{\sqrt{2x}}=\frac{\sqrt{8x^2}*\sqrt{2x}}{2x}}=\frac{\sqrt{16x^3}}{2x}=\frac{4x\sqrt{x}}{2x}=\boxed{2\sqrt{x}}$
