suppose the lateral area of a right circular cone and the area of a sphere is equal 64π inches^2. if the radius of the sphere and the radius of the base of the cone are equal, what is the volume of the cone?

Best ResponseYou've already chosen the best response.2It would be essential in finding the volume...

Miyuru

Best ResponseYou've already chosen the best response.2To find the total area multiply the area of triangle by 6 + area of hexagon..

Best ResponseYou've already chosen the best response.1volume of pyramid = 1/3* area of hexagon * height

Best ResponseYou've already chosen the best response.1yeah ... looks like that's correct!!

Best ResponseYou've already chosen the best response.0Gee! thanks a lot!!!!! but how is this? find the volume of the region outside the pyramid and inside the prism.

experimentX

Best ResponseYou've already chosen the best response.1find the volume of pyramid ... find the volume of prism ... subtract 1 from 2

Miyuru

Best ResponseYou've already chosen the best response.2Volume = \[(\frac{10*9}{2}*6)*\frac{1}{3}*12  (\frac{10*9}{2}*6*12)\]

experimentX

Best ResponseYou've already chosen the best response.1lol ... you did the opposite? is height 12??

Miyuru

Best ResponseYou've already chosen the best response.2I took the height of the pyramid...

experimentX
 3 years ago
Best ResponseYou've already chosen the best response.1should be something like this if 12 is height \[  (\frac{10*9}{2}*6)*\frac{1}{3}*12 + (\frac{10*9}{2}*6*12) \]

Best ResponseYou've already chosen the best response.0so 4320 is the volume?=)

gandako

Best ResponseYou've already chosen the best response.0What is the area of the base and the height?

Miyuru

Best ResponseYou've already chosen the best response.2Yeah @gandako U are correct.. volume=4320

Best ResponseYou've already chosen the best response.2I found the height from the triangle drawn above.. x=12

Best ResponseYou've already chosen the best response.0but how about the are of the base @Miyuru ?

Miyuru

Best ResponseYou've already chosen the best response.2Base = side of the hexagon

Miyuru

Best ResponseYou've already chosen the best response.2From which step are you confused?

gandako

Best ResponseYou've already chosen the best response.0here: volume of pyramid=1/3 * area of the base *height how can get the are of the base?

Miyuru
 3 years ago
Best ResponseYou've already chosen the best response.2Here the base is the hexagon and it's area is six times the area of a triangle...
