Question

Answer 1

Hey frnd....

Thanks for asking this question.
Here is your answer.....

✨Volume of Cylinder ✨
Height = 20 cm
Internal radius = 26 cm
External radius = 30 cm

Volume of hollow cylinder = πh(R²-
r²)
=> π × 20×{(30)²- (26)²}
=> 22/7 × 20 × (900-676)
=> 22/7 × 20 × 224
=> 22 × 20 × 32
=> 14080 cm³

Hope this would help you.
