The volume of a cone, V, is represented by , where r is the cone’s radius and h its height.

1 answer:

8 0

So the height will equal 95.50 inches.

So if you double the height the volume is 1800cm3 and that is double the original volume

And if you double the height the volume is 3600cm3 and that is the triple the original volume

I think that is 248 min in one day because 24/5 is 4.8. 4hours and 8 min. 4 times 60 is 240. 240 plus 8 is 248 this is what I think.

Please help !!!!!!!!!

vodka [1.7K]

Answer:

A= 41° a=9.84... b=11.32...

Step-by-step explanation:

given B = 49° and C = 90°

and A + B + C = 180

so 49+90+A=180

A= 41°

we also know c (small) is 15 units

and maybe you know this SOH CAH TOA? no, i'm not calling anyone names :P this is just the mnemonic to memorize how sin , cos and tan fit sin(Ф)=Opp/Hyp Cos(Ф)=Adj/Hyp Tan(Ф)=Opp/Adj

Hyp is the hypontenuse of the triangle ( the long side). Opposite (Opp) means the side opposite from what ever angle you are starting at..adjacent (Adj) means what ever angle is next to where you are starting from.

use Cos(49) to find the side a

a is an adjacent side to the 49 angle. We know the Cos and we know the Hyp .. so solve for adj...

Cos(Ф)=Adj/ Hyp

Hyp*Cos(Ф)=Adj

15*Cos(49)= Adj

9.84...=Adj=a

now lets' use sin for the opposite side or b

sin(Ф)=Opp/Hyp

Hyp*Sin(Ф) = Opp

15*sin(49)= Opp

11.32...= Opp =b
