Question

A metallic hemisphere is melted and recast in the shape of a cone with the same base radius (R) as that of the hemisphere. If H is the length of the cone, then :
a. H = 2R
b. H = 2/3 * R
c. H = Sq root of (3R)
d. H = 3R​

Answer 1

Answer:

b is the correct option

Step-by-step explanation:

1/3pi×r³=1/2 pi r²h

1/3r=1/2h

h= 2/3×r

r is the radius of the figures
