Question

If the volume of a cylindrical jar and a hemispherical bowl is equal and the radius of cylindrical jar and hemispherical bowl is equal to 9 cm, then height of cylindrical jar is​

Answer 1

Answer:

height of cylindrical jar = 6cm

Step-by-step explanation:

vol(cylinder) = vol( hemisphere )

radius of cylinder and hemisphere = r

r = 9cm

vol( cylinder ) = πr^2h ( where h is height of cylinder )

vol( hemisphere ) = 2πr^3/ 3

πr^2h=2πr^3/3

h=2r/3 [ πr^2 cancelled from both side ]

h = 18/3

h = 6 cm
