The volume is 508.94 cm^3

volume of a cone = \pir²(h/3)

we are given the height (6cm) and radius (9cm) so we can plug in our values

\pi9²(6/3)

\pi81(2)

\pi162

since it is asking for an exact value for the volume, you can leave pi

v = 162\pi cm³

hope this helped

David's phone bill each month is $30. He is also charged $0.10 per GB of data he uses. If his phone bill in July was $42, how ma
Aleonysh [2.5K]

Answer:

120

Step-by-step explanation:

Okay so the equation would be like this
30 + 0.10g = P

g = GB of data used

P = Total Price

Let's work this out now!

So. If his total bill was $42 lets subtract the 30 that comes out every month automatically, now we are just left with 12, if each GB costs 0.10 then all you would do to find out how many GB he used is do 12/0.10 (which is really just 12*10) which will get you 120

Meaning that he used 120 GB

(That's a lot!)

Elodia [21]

<u>Answer</u>


26.6°


<u>Explanation</u>

You are required to use the trigonometric ratio, sine, to find that angle.

SinФ = opposite/hypotenuse


sin Θ = 2.6/5.8

= 0.4483


The angle Θ = Anti-sine(0.4483)

= 26.633°


The angle the slide makes with the ground, correct to one decimal place is 26.6°
