A cylinder has a diameter of 20 inches and a height of 9 inches. Find the volume of the cylinder, round to the nearest tenth.

Respuesta :

The formula for the volume of a cylinder is
  V = π·r²·h

Filling in the given information, your cylinder's volume is
  V = π·(10 in)²·(9 in)
  V = 900π in³
  V ≈ 2827.4 in³
