Question

A solid metallic sphere of radius 9cm is melted and recast into a solid right circ is the curved surface area (in cm2) of the cone?

Is that so?
hmm​

Answer 1

Answer:

Radius of sphere R=15 cm

Dimensions of cone r=2.5 cm h=8 cm

When a solid is converted from one form to another, the amount of volume remains the same. Let x number of cones can be melted.

Number of cones, x=

Radius of sphere R=

$15 cm$

Dimensions of cone r=

$2.5 cm$

$h=8 cm$

When a solid is converted from one form to another, the amount of volume remains the same. Let x number of cones can be melted.

Number of cones, x=

$\frac{volume \: of \: sphere}{volume \: of \: 1 \: cone}$

$\frac{4\pi}{3} {15}^{3} \\ \frac{1\pi}{3} {2.5}^{2} (8)$

=

$\frac{4 {(15)}^{3} }{2.5 {}^{2}8 }$

=

$270 \: cones$
