By rounding off to the nearest whole number, the volume of the cone is 509 cubic centimeters.
As we know, the formula for the volume of a cone is =
cubic units
And as per the question, the radius of the cone= 9 cm
Height of the cone= 6 cm
Now, putting the values into the formula,
Volume = (1/3)*π*(9*9)^2*6= 508.68 cubic centimeters
By rounding off, this will be equal to 509 cubic centimeters.
