Answer:
Step-by-step explanation:
Volume of cone = volume of sphere
1/3× pie× r sq×h= 4/3× pie× r cube
1/3 × 22/7× 4×4×7= 4/3×22/7×r×r×r
4×7= r×r×r

Answer:
Step-by-step explanation:
Volume of cone = volume of sphere formed ....(i)
Volume of cone = 1/3 * pi*r^2*h
= 1/3 * pi *4*4*7
Volume of sphere = 4/3 * pi * r^3
As per eq. (i)
1/3 * pi * 4 * 4 * 7 = 4/3 * pi * r^3
['pi' on both sides cancel each other and so does the denominator '3']
4*4*7 = 4* r^3
4*7 = r^3
r = cuberoot 28 = 3 cm (approx.)

toh wahi mujhe chahiye uska exact value kya aayega
3.04
how you had taken the exact answer
I think that is notthe exact value
can you tell me the method to find out cube root because I had tried to do this but the final answer had not come that is why I posted this question
28 ka nearest cube root number... It is 3.. so quotient ka pehla sthaan '3'... ab reminder = 1... Now we have to put 3 zeors to the reminder...
aage
so we get 1000... and in quotient put a 'decimal' and write '0'... so its now 3.0 with reminder 1000
mujhe laga ki last ke 3 digit ko lete h
aage
