Use cavalieri's Principle to calculate the exact of an oblique cylinder with a radius of 10 meters and a height of 11 meters.

Readme [11.4K]

Am I to assume this is for volume? The volume formula for a cylinder...oblique or not...is V = 1/3pi r^2 h. Cavalieri's principle tells us that the formulas for both are the same. So V = 1/3*pi*100*11 and V = 366.67 pi

Reference angle for -19pi/6?

kow [346]

$\bf \cfrac{19}{6}\implies 3+\cfrac{1}{6}
\\ \quad \\\\
\cfrac{-19\pi }{6}\implies -\left(3\pi +\cfrac{1\pi }{6} \right)\impliedby clockwise
\\ \quad \\\\
or\implies -\left(2\pi +\pi +\cfrac{\pi }{6} \right)$

go that much "clockwise", you'll end up at the 2nd quadrant,
the reference angle, is its reflective angle on the 1st quadrant

How to convert 750 in ^3 to yd^3

____ [38]

$\bf \stackrel{\textit{we know that }}{1yd=36in}\implies \stackrel{\textit{therefore}}{(1yd)^3=(36in)^3}\implies \stackrel{\textit{distributing the exponent}}{1^3yd^3=36^3in^3}\\\\\\1yd^3=46656in^3~\hspace{8em}therefore\\\\\\750 \underline{in^3} \cdot \cfrac{1yd^3}{46656 \underline{in^3}}\implies \cfrac{750 yd^3}{46656}\implies \cfrac{125 yd^3}{7776}~~~~\approx~~~~ 0.016075~yd^3$

In a certain clothing store, 6 shirts and 3 ties cost $79.50, and 3 shirts and 2 ties cost $41. Determine the cost of each tie.

Genrish500 [490]

6x + 3y = 79.5
3x + 2y = 41 y = -3/2x + 41/2 y = -1.5x + 20.5

6x + 3(-1.5x + 20.5) = 79.5
6x - 4.5x + 61.5 = 79.5
1.5x + 61.5 = 79.5
1.5x = 18
x = 12

Each shirt costs $12.
Now insert that number into the x to find the cost of each tie.

3(12) + 2y = 41
36 + 2y = 41
2y = 5
y = 2.5

Each tie costs $2.50.
