Since the formula for the volume of a cone is V = (1/3)*π*r^2*h, we need to multiply the fraction 1/3, the value of pi (assuming you meant 3.14), the radius squared, and the height together to get the volume. Diameter is radius times 2, so to find the radius, multiply the diameter by .5, ending up with 3. 3^2 is 9. 1/3*3.14*9*6 is equal to 56.52.
Volume of a cone = (πr²h)/3 = [π6²(6)]/3 = 36*6π/3 = 216/3π cm3 = 72π cm3
Explanation
A cone is a solid that has a circular base and a single vertex. To calculate its volume you need to multiply the base area (area of a circle: π * r²) by height and by 1/3: volume = (1/3) * π * r² * h.
