This right circular cone has a volume of 75π cubic inches. The height of the cone is 9 inches. What is the length of the radius?

sukhopar [10]

$\bf \textit{volume of a cone}\\\\
V=\cfrac{\pi r^2 h}{3}\quad 
\begin{cases}
r=radius\\
h=height\\
-----\\
V=75\pi \\
h=9
\end{cases}\implies 75\pi =\cfrac{\pi r^2\cdot 9}{3}\implies 75\pi =3\pi r^2
\\\\\\
\cfrac{75\pi }{3\pi }=r^2\implies 25=r^2\implies \sqrt{25}=r\implies 5=r$

Answer:

The probability of a person having a driving accident while intoxicated is 0.07

Step-by-step explanation:

Hi, well, let´s put this on a formula, I think it is the best way to explain it.

$P(A+I)=P(A)+P(I)-P(AorI)$

Where:

P(A+I) = Probability of having a driving accident while intoxicated.

P(A) = Probability of a person of having an accident.

P(I) = Probablity person being intoxicated.

P(A or I) = Probability of a person for being intoxicated or having an accident.

Therefore, things should look like this:

$P(A+I)=0.12+0.32-0.37=0.07$

So, the probability of a person having a driving accident while intoxicated is 0.07.

Best of luck.

Which angle pairs are supplementary? Check all that apply

polet [3.4K]

Answer:

The pairs of supplementary angles are

∠4 and ∠3 , ∠3 and ∠6 , ∠4 and ∠5 .

Step-by-step explanation:

Definition of supplementary angles

When sum of two angles are 180° they are called supplementary angles .

As figure given in the question

∠3 = 90°

Thus

∠3 + ∠6 = 180 °

(By using Linear pair property)

∠4 + ∠5 = 180 °

(By using Linear pair property)

∠3 + ∠4 = 180 °

(By using Linear pair property)

Therefore the pairs of supplementary angles are

∠4 and ∠3 , ∠3 and ∠6 , ∠4 and ∠5 .
