What is the volume of the cone to the nearest tenth?

Kisachek [45]

Answer:

366.5cm³

Step-by-step explanation:

1. Determine the height and radius of cone.

2. Using the formula for the volume of a cone input where there is an h and r.

3.Where it says Area of base, it is talking about the circular base and that you need to find its area. (π×r²), you already have the radius so you put it in the formula and solve (π×5²)

4. Once you have the area of the base you can now completely solve. Multiply ⅓×(78.54)×14

Solve the linear equation: 3.4 + 2(9.7 – 4.8x) = 61.2 What are the possible steps involved in solving this equation? Check all t

Leno4ka [110]

The answers for the exercise shown above are the second option, the third option, the fifth option and the sixth option, which are:
2) <span>Distribute 2 to 9.7 and −4.8x.
3) Combine 3.4 and 19.4.
5) Substract 22.8 from both sides.
6) Divide both sides by −9.6
The steps are shown below:
</span><span>3.4+2(9.7-4.8x)=61.2</span>
3.4+19.4-9.6x=61.2
22.8-9.6x=61.2
228-22.8-9.6x=61.2-22.8
-9.6x=38.4
-9.6x/-9.6=38.4/-9.6
x=-4

It is estimated that light takes 110,000 years to travel the full distance across our galaxy

stepladder [879]

$\bf \stackrel{light~speed}{3.0\times 10^8}ms^{-1}\implies \stackrel{light~speed}{3.0\times 10^8}~\frac{m}{s}\implies 300,000,000~\frac{m}{s}\\\\
-------------------------------\\\\
\textit{how many seconds in a minute?}\qquad 60
\\\\\\
\textit{how many seconds in }\stackrel{1~hr}{60~minutes?}\qquad 60\cdot 60
\\\\\\
\textit{how many seconds in }\stackrel{1~day}{24~hrs}?\qquad 60\cdot 60\cdot 24
\\\\\\
\textit{how many seconds in }\stackrel{1~year}{365~days}?\qquad 60\cdot 60\cdot 24\cdot 365$

now, it takes 1 second for light to travel 300,000,000 meters.

if we know it takes light 1 second to go 300 million meters, then in 365 days or a year, or 60*60*24*365 seconds, it will then travels

300,000,000 * 60 * 60 * 24 * 365 meters in 1 year,

how about in 110,000 years, how many meters has it travelled?

300,000,000 * 60 * 60 * 24 * 365 * 110,000 that many meters.

we know she travels the Milky Way in 110,000 years or 60 * 60 * 24 * 365 * 110,000 seconds

and we know that 110,000 years is 3468960000000 seconds, so

if it travels 300000000 meters in only 1 second, in 3468960000000 seconds, it will travel then (300000000) * (3468960000000) meters

or 1040688000000000000000 meters.
