Question

If the volume of cylinder is 1024 CM square find the height if the radius is 7 cm

Answer 1

Volume of the cylinder (V)

=1024cm³

Radius (r)= 7cm

Let the height = h cm

We know that ,

πr²h = V

=> (22/7)×7²×h = 1024

=> 22×7×h = 1024

=>h=1024/(22×7)

=> h ≈ 6.65cm

Therefore,

height of the cylinder = 6.65cm

Answer 2

Volume of cylinder is 1024 cm

Radius of cylinder is 7cm

1024=22/7×7×7×h

1024=22/7×7×7×h

1024=153.86×h

h=1024/153.86

h= 6.65
