Answer:
6xy^3 +12xy^2 z
Step-by-step explanation:
3xy^2 (2y+4z)
Multiply
3xy^2 * 2y + 3xy^2 *4z
common factors
3xy^3 +3xy^2 *4z
Multiply
6xy^3 +12xy^2 z
Its a Parellelogram, as the opposite sides are equal.
if the minute hand of the <u>circular clock</u> is 28 inches, that simply means its radius is 28.
![\bf \textit{area of a circle}\\\\A=\pi r^2~~\begin{cases}r=radius\\[-0.5em]\hrulefill\\r=28\end{cases}\implies A=\pi 28^2\implies A=784\pi](https://tex.z-dn.net/?f=%5Cbf%20%5Ctextit%7Barea%20of%20a%20circle%7D%5C%5C%5C%5CA%3D%5Cpi%20r%5E2~~%5Cbegin%7Bcases%7Dr%3Dradius%5C%5C%5B-0.5em%5D%5Chrulefill%5C%5Cr%3D28%5Cend%7Bcases%7D%5Cimplies%20A%3D%5Cpi%2028%5E2%5Cimplies%20A%3D784%5Cpi)
so it covers that much in 1 rotation, so in 4 rotations that'd be 4(784π) => 3136π.
