Question

In a test tube diameter=2cm, height=15cm then what is the capacity of test tube. (π=3.14)

Answer 1

HEYA HERE IS YOUR ANSWER

Answer 2

Diameter of test tube = 2 cm

Radius = 2/2 = 1 cm

Height, h = 15 cm

Hence, capacity of test tube = πr^2*h + 2πr^3/3

                                               = 3.14*1*1*15 +2*3.14*1*1*1/3

                                               = 47.1 + 2.093 cm3 = 49.193 cm3
