<h3>Volume of the cylinder:</h3>

v = \pi {r}^{2} h

v = 3.14 \times  {2}^{2}  \times 3

v = 37.68 \:  {cm}^{3}

<h3>Volume of the rectangular prism:</h3>

v = lwh

v = 6 \times 5 \times 7

v = 210 \:  {cm}^{3}

<h3>Total volume:</h3>

v = 37.68 + 210

v = 247.68 \:  {cm}^{3}

Help! Given that tanθ=-1, what is the value of secθ, for 3π/2&lt;θ&lt;2π?
user100 [1]

Answer:  Choice B)  \sqrt{2}

Work Shown:

\sec^2(\theta) = \tan^2(\theta) + 1\\\\\sec^2(\theta) = (\tan(\theta))^2 + 1\\\\\sec^2(\theta) = (-1)^2 + 1\\\\\sec^2(\theta) = 2\\\\\sec(\theta) = \sqrt{2}\\\\

Note: secant is positive in quadrant Q4, when theta is between 3pi/2 radians and 2pi radians (270 degrees and 360 degrees). So that's why we don't consider the minus form of the plus minus.

Which of the following is a subset of {1, 3, 5, 7, 9}?
MakcuM [25]
In mathematics, a set A is a subset of a set B, or equivalently B is a superset of A, if A is "contained" inside B. I belive the correct answer from the choices listed above is the second option. It is the set  {5, 6, 7} that is a subset of <span> {1, 3, 5, 7, 9}. Hope this answers the question</span>

Where is the exact volume of the sphere
baherus [9]

\bf \textit{volume of a sphere}\\\\ V=\cfrac{4\pi r^3}{3}~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ r=12.3 \end{cases}\implies V=\cfrac{4\pi (12.3)^3}{3}\implies \stackrel{\pi =3.14}{V\approx 7790.83}
