Question

Find the height of a cylinder with radius 15 cm whose volume is 3 times the volume of a sphere of the same radius

Answer 1

Answer:

60cm

Step-by-step explanation:

vol. of cylinder =πr^2h

vol. of sphere=4/3πr^3

given that vol. of cylinder=3×vol. of sphere

πr^2h=3×4/3×r^3×π

h=4r

h=4×15=60cm

Answer 2

Step-by-step explanation:

3*volume of sphere= volume of cylinder

3*4/3πrrh=πrrh

4*22/7*15*15=22/7*15*15*h

4=h

height of cylinder=4 cm
