Question

the diameter of the base of a right circular cylinder is 42 cm and its height is 12 cm find the volume​

Answer 1

Answer:

volume of a cylinder= πr^2h

here ,r= d/2 = 42/2 =21

h= 12

so, volume= 22/7×21×21×12

=22×3×21×12

=17424

Answer 2

Answer:

16632

Step-by-step explanation:

volume of Cylinder = 2πrh.

hear,r=d/2 = 42/2 = 21

h=12

so volume = 22/7 x 21 x 21 x12

= 16632
