Question

An oil drum having diameter of 800 mm and height of
50 mm. The volume of drum is ....... ​

Answer 1

r = 400mm

h = 50mm

Volume of Drum = $\pi$r²h

                            = 3.14 * 400 * 400 * 50

                            = 251200 mm³

Therefore, the Volume of drum is 251200 mm³.

Thank u

Answer 2

Answer:

Step-by-step explanation:

10mm = 1cm

Height = 5cm

Diameter = 80cm

Radius = 1 / 2 x 80

= 40 cm

Volume of cylinder = πr^2h

= 22 / 7 x 40 x 40 x 5

= 22 x 5.71 x 40 x 5

= 25124

Therefore the volume will be 25124cc
