Question

(iv) The figure shows a test tube of diameter 2 cm. The test tube has a
cyclíndrical part and hemisperical part with equal radii. If the total
height of the test tube is 14 cm, then what is the height of the
cylindrical part?
​

Answer 1

Answer:

H of cylinder part = 13 cm

Step-by-step explanation:

Total h of test tube = 14 cm

There is a hemisphere as the base of test tube

Then, h of hemisphere = 1 cm (as equal to radius)

So, H of cylindrical part = 14-1 = 12 cm

(total h of test tube - h of hemisphere)
