## melmel 3 years ago Find the dimensions of the largest right cicular cone that can be inscribed in a sphere of the radius 12 inches.

1. melmel

try it master

2. melmel

??

3. mathslover

this also include calculus right?

4. sauravshakya

right

5. mathslover

ok first of all when will be the right circular cone will be largest when radius = 12 inches

6. melmel

yes

7. mathslover

very confusing .. @Callisto

8. melmel

yeah super haha

http://www.themathpage.com/acalc/applied.htm check out problem no. 5 its similar but in it we want to find volume

10. mathslover

yes i also searched for it .but found only volume :(

@mathslover i think in this case we'll take lateral area and total area LA= pi*r*l TA= LA + BA where LA= lateral area BA = base area TA= pi*r*l + pi*r^2 =pi*r(l+r) now we can max or min its dimensions easily

Hmn @annas I am seriously diverged in a complicated question .. well it seems that you are going right but not sure

13. annas

ok...
