Question

A hollow spherical ball whose inner radius is
4 cm is full of liquid. If this liquid is trans-
ferred into 2 equal conical cups of height 2
cm each, then the radius of the base of the
cup is :
(a) 8 cm
(b) 12 cm (c) pie cm
(d) 8 pie cm​

Answer 1

Answer:

volume of cone =1/3πr²h

volume of sphere = 4/3πr³

Hence,

1/2x(volume of Sphere) = Volume of cone

1/2x4/3π(4)³ = 1/3xπr²x 2

r² = 64

r = 8cm

ANSWER:- (a) 8cm
