Answer 1

Answer:

13,860 cm²

Step-by-step explanation:

You know that, volume of cylinder= πr²h

Radius (r)= 21cm

Height (h)=10 cm

Volume= 22/7×21²×10

= 22/7×441×10

22×63×10

= 13,860 cm²

Answer 2

Answer:

Firstly we want to know the formula of

volume of cylinder =

V = pie r square h

so let's put the values

22/7×21×21×10

so we get answer

13860

Step-by-step explanation:

its very easy

hope its helpful
