The perimeter of a square can be represented by the

kompoz [17]

Answer:

Step-by-step explanation:

perimeter of a square = 4 x length (L)

8x - 10 + 8x - 10 = 4L

rearrange the expression

8x + 8x - 10 - 10 = 4L

16x - 20 = 4L

divide both sides for L to stand alone

(16x - 20)/ 4 = 4L/4

(16x - 20)/4 = L

How does the volume of a cylinder change when it’s diameter is doubled

zavuch27 [327]

Recallin that, the diameter is twice as long as the radius, namely the radius is half the diameter, so, if the diameter is doubled, the radius is also doubled.

$\bf \textit{volume of a cylinder}\\\\
V=\pi r^2 h\quad 
\begin{cases}
r=radius\\
h=height\\
-----\\
r=\stackrel{doubled}{2r}
\end{cases}\implies V=\pi (2r)^2 h
\\\\\\
V=\pi (2^2r^2)h\implies V=\pi 4r^2 h\implies V=4~(\pi r^2 h)$

notice, the new volume is 4 times (πr² h), namely 4 times the original.
