Question

11. A cylinder has a height of
50 cm and diameter of 42
cm. Find it's volume.​

Answer 1

Answer:

h=50cm

r=42/2=21 cm

ar of cylinder= πr^2

ar= 22/7*21*21

ar=22*3*21

ar=1386cm^2

Answer 2

Answer:

63900cm3

Step-by-step explanation:

volume of cylinder = πr^2h

D=42

R=42/2

=21

so

22/7*21*21*50

22/7*3*21*50

1386*50

63900cm3
