Question

Calculate the height of 385cm3 of water inside a cylinder of diameter 7cm

Answer 1

Answer:

Height of the cylinder = 17.5 cm

Step-by-step explanation:

Given:

volume of the cylinder = 385cm³

Diameter of the cylinder = 7cm

So, it's radius = 7/2cm

And, let the height be 'h'

Now, Volume of a cylinder = 2πrh

So, putting in the given values. We get,

385 = 2×22/7×7/2×h

385 = 2×11×h

385 = 22×h

385/22 = h

So, h = 17.5 cm

Answer 2

Answer:

Step-by-step explanation:

V= π²h

385= 3.14×(3.5)²h

385=38.5h

h=385/38.5
