Answer:

The answer is 117.3 $in^{3}$ .

Step-by-step explanation:

To solve for the volume of the cone, use the cone volume formula, which is V = $\frac{1}{3} \pi r^{2} h$ .

Next, plug in the information given from the problem, and the formula will look like V = $\frac{1}{3} (\pi) (4 in^{2}) (7 in)$ .

Then, solve the equation, and the answer will be 117.3 $in^{3}$ .

Cos90degrees cos30 degrees + sec-squared45degrees sin30degrees - cos270degrees sin180degrees

yawa3891 [41]

Step-by-step explanation:

$\cos 90 \cos 30 + \sec^2 45 \sin 30 - \cos 270 \sin 180$

But we know that

$\cos 90 = \cos 270 = \sin 180 = 0$

and

$\sin 30 = \dfrac{\sqrt{3}}{2} \:\:\text{and}\:\: \sec 45 = \sqrt{2}$

so this leaves us with just

$\sec^2 45 \sin 30 = (\sqrt{2})^2 \left(\dfrac{\sqrt{3}}{2} \right)= \sqrt{3}$

A flask containing 9.5 mL of a liquid weight 157.2 g with the liquid in the flask and 148.4 g when empty calculate the density o

agasfer [191]

Density = Mass/Volume
Mass = 152.7 gVolume = 9.5 mL
Since the mass gram correspond to the volume mL, then we can apply the formula:
Density = 152.7/9.5 = 16.074 g/mL (Or kg/L)
