Acircular cone with a base of radius has been cut as shown in the figure.

what is the height of the smaller top cone?

It is measure that height of smaller cone = 6 unit  

Step-by-step explanation:

From the figure it is given as,

Slant height of larger cone = L = 8+5 = 13 unit

Slant height of smaller cone = l = 8 unit

Radius of larger cone = R = 5 unit

Let the height of larger cone = H unit

And  the height of smaller cone =h unit

Now, clearly from figure, h =

From slant height formula

   L² = H² + R²

Or, 13² = H² + 5²

Or, H² = 13² - 5²

or, H² = 169 - 25 = 144

∴   H = √144 = 12 unit

Hence Height of smaller cone = h =

                                                     h =

Or,                                                 h = 6 unit

Hence It is measure that height of smaller cone = 6 unit    Answer

3, 12, 48, 384, 1536, 6144, 24576, 98304

step-by-step explanation:

just keep timing it by 4.

i think the answer is a.( -3, -1 )
