Geometry question

Answer 1

Sure :)

Answer 2

A sphere of diameter 12.6 cm is melted and cast into right circular cone of height 25.2 cm.
find the diameter of the base of the cone?

Answer 3

\(a.)158.76~~cm\\
b.)79.38~~cm\\
c.)39.64~~cm\\
d.)none\\\)

Answer 4

books gives answer as \(b.)79.38\)

Answer 5

equate vol sphere 4/3*(pi)r^3 to cone =pi(R^2)/3*(h) of course the radius is different
4/3(pi)(12.6/2)^3= pi(d^2)/4* 25.2 solve for Dia.=?

Answer 6

d=12.6 ?

Answer 7

that's what I get so answer D
