Question

a solid cone of height 14cm having its base radius 7cm is melted and recast to form a solid hemisphere calculate the radius of the solid hemisphere​

Answer 1

Step-by-step explanation:

In cone

h=14cm

R=7cm

In sphere

r=?

volume of cone = volume of hemisphere

1/3 πR^2h = 2/3 πr^3 1/3 × 22/7 × 7 × 7 × 14 = 2/3 × 22/7 × r^3

2156/3 = 44/7 r^3

49×7 = r^3

283 = r^3

r = cube root of 283

r = 7

therefore ,

radius of the solid hemisphere is 7cm
