Sir, answer was rh ÷ (h + r); where r is Radius of cone and h is height of cone??? By using similarity of the triangles formed by RADIUS OF SPHERE and RADIUS OF CONE

[@AdiTripathiJi]

Sir in order to find radius of sphere, i will treat cone as triangle and sphere are as circle and will apply formula Area of triangle / semi perimeter of triangle = radius Area of triangle =(1/2) r × H Perimeter 2(r+l) Semi perimeter = r+l Radius of sphere =r×h/2(r+l)

How to do the radius of the sphere.????

[@lostgalaxy9084]

R=h×1/3

[@irreplaceable_girl]

Thank you sir...

[@descentgaming2943]

Best explanation

[@ajayverma2650]

h/2 will be the radius of this circle . is this correct sir?

[@aviralverma1045]

Sir at first we have to find out two triangle and then make them similar after it we have to apply ratio of similarity and then radius of the sphere is comes out to be equal to the radius of the cone

sir you are the best I like your teaching instead of my school teacher

Sir, Radius of largest sphere that can be fit in cone of radius 'r' , height 'h' and slant height 'l' can be found by given formula R = r(l-r) ÷ h

[@EDUCATIONISMUST]

Frustom ka height ,,sphere ka diameter ka kaam kregaa,,aur diameter ka half krke radius nikaaal skte hai sphere ka,,simple

[@siddhi4831]

I don't think so because yahan frustum ka baat nhi cone ka baat ho rha hai and cone ka complete height thodi na aa rha hai jo half krke nikalenge

[@adityadadhich1910]

R=rh/l+r property of area of triangle(perimeter of triangle mulitly inner radius /2

[@prakulchauhan2924]

why invent frustum formula while we use for finding suface area of remaing part like area = suface area of bigger cone - surface area of smaller cone
