This question is asking for the volume of the cone. The formula is 1/3π r²h where r is radius and h is height. First we must find the radius by dividing the diameter in half, giving us 3.5 Now we plug our values into the formula like this:
1/3 π r²h 1/3 π3.5² 13
This gives us the answer of 166.76mL or 166.8mL depending on how you want to round it.
