462

Step-by-step explanation:

Base=π × r²

=> π × 3.5²

=>38.48

Volume:

Base times height

=>38.48 x 12

=>461.81

Answer:

  • 426m²

Step-by-step explanation:

Given ;

  • radius = 3.5m , hieght = 12m

Volume of cylinder = π2²h

  • 22/7 × ( 3.5 )² × 12
  • 22/7 × ( 7/2 )² × 12
  • 22/7 × 7/2 × 7/2 × 12
  • 462m²

Volume of the cylinder is 426m².
