Question

calculate the radius of the cylinder whose height is 21 cm and the volume is 1100cm cube

Answer 1

Step-by-step explanation:

Volume of cylinder = πr²h

1100cm³ = 22/7 × r² × 21cm

1100 cm³ = 22 × r² × 3cm

1100/(22 × 3) = r²

50 /3 = r²

√(50\3) = r

Answer 2

the answer is given above : 50/3
