Answer 2

Step-by-step explanation:

given : a test tube has a diameter of 20mm

height = 15 cm

to find: capacity of test tube

r = d/2

r =20/2

r = 10mm

h =15cm =15X10 =150mm

Cylinder formula

$v = \: \pi \: {r}^{2} h$

$v = 3.14 \times {10}^{2} \times 150$

$v = 3.14 \times 100 \times 150$

v = 47100 mm

v = 47100/10

v = 4710
