Best ResponseYou've already chosen the best response.1So the sphere must have had the same volume. But the volume of a sphere is: \[V=\frac{4}{3}\pi r^3=80\pi\]

Best ResponseYou've already chosen the best response.1Did you use 20 for the radius instead of 40?

hihi

Best ResponseYou've already chosen the best response.0i added it up and the answer was: 20096 cm

hihi

Best ResponseYou've already chosen the best response.0i think i might have used it

hihi

Best ResponseYou've already chosen the best response.0i did area x height to get the answer so:

Mertsj

Best ResponseYou've already chosen the best response.1So what did you get for the area of the triangle?

hihi

Best ResponseYou've already chosen the best response.0i really got 11.994 so i rounded to 12, would that be right?

hihi

Best ResponseYou've already chosen the best response.0what would the answer be then?

Mertsj

Best ResponseYou've already chosen the best response.1Here is the triangle: dw:1328744624957:dw

hihi

Best ResponseYou've already chosen the best response.0so height equals=3.464, then to get area base X height so 3.464X2

Mertsj

Best ResponseYou've already chosen the best response.1\[A=\frac{1}{2}(4)(2\sqrt{3})=4\sqrt{3}=6.93\]

Mertsj

Best ResponseYou've already chosen the best response.1That is the area of the base. To get the volume, you have to multiply that by the height.

hihi

Best ResponseYou've already chosen the best response.0so the answer is approximately 24?

Mertsj

Best ResponseYou've already chosen the best response.1See that picture? You have to take the area of the triangle and multiply it by the height of the prism which is 10

hihi

Best ResponseYou've already chosen the best response.0but i did 6.93x the height, which is 3.464, and i got 24, is that right?

Mertsj

Best ResponseYou've already chosen the best response.1Do you see that picture?????? The HEIGHT OF THE PRISM IS 10.

Mertsj

Best ResponseYou've already chosen the best response.0ya i think 7 and 4 are more reasponsible, considering thats what i got as well. Then i did 7X4+2X5, getting 38 m
